[@zatrox9438]

Why didn't you post this video to silicon dojo channel?

[@jessen00001]

You are Eli the computer GUY Now Milk that cow my mann

[@lastchance6536]

Great videos man, keep em coming 😁

[@damospearzo1032]

Living in Australia may make the last bit too hard, but keep these videos up please.

[@donniehdea9281]

**ok, so you need every variation of url including the https part ** tried for nearly half a day to get dns block to work, works for ping but chome and firefox still connect, am on debian, why is it still able to connect?

[@josephsagotti8786]

finally, eli has returned to greatness.

[@rohanofelvenpower5566]

yo elliot! this is the years of the elliors haha

[@networkdude1332]

Agreed!

[@ropperish]

Nice!! Eli The Computer Guy is Back!!!

[@One-Crazy-Cat]

Yeah nice to see him not just whining about the news.

[@franko3p]

The best

[@smmmokin]

Strange. Louis Rossman talked about Eli and I saw a guy talking about the world. Now he shifted and he talks about things I've always wanted to know about. You say he's back but maybe it was good he took a U-turn. Not sure I'd be here if he didn't.

[@dakoderii4221]

Like the old days but remastered with a new graphics engine and DLC.

[@erelpc]

the latest expansion pack.

[@gabakusa]

lol

[@joperez1980]

A good upgrade from the basement orange-skin pack.

[@bopierson2171]

best free DLC ever!!

[@erelpc]

@@bopierson2171 free expansion pack

[@by9798]

I couldn't believe my eyes when I seen a DNS video by Eli The Computer Guy in my feed! Your videos taught me everything I needed to dive into an IT career 8 years ago. I'm so hype!!!

[@anthonym7602]

One of the best presenters for IT that I have found. These recordings are immensely helpful for learning and reviewing topics I explore in my post secondary.

[@MadrasaTechOfficial]

Welcome Back the Eli we know and the voice we like. You laterally took me back 7 years ago with that voice tone :D when I used to watch the ELI we all love.

[@flying_free]

I like the recordings after since they are more focused and as you mentioned presenting it to the video after stepping through the seminar live can help raise additional clarification points to pass along. Much appreciated.

[@rayn1ful]

i love your videos Eli , your videos helped get me through my cancer and chemo back in 2013 to 2015. i of course still watch and enjoy them today and will continue to do so.

[@user-lv3yp6jd4i]

Elie, I am glad that you have returned to that type of content! I want you to know that you are really good at this. Me, personally speaking, have watched a lot of your old videos, about Networks, Servers and IT in general. With the knowledge I gained from your content, I managed to go to a local IT course, then get a certificate and now I work as a System Administrator. 3-4 years ago I only knew how to use google and youtube on a computer, quite literally. So keep it going, you really are good at what you are doing, and you know how to explain complex concepts understandably !

[@samimkazi1608]

Yes! Now feeling well to see you as mentor of IT Technology.

[@rhadl1]

Thank you for posting this! I'm looking forward to more educational videos! I'm relatively new to the I.T. World and coming across your channel has been exceedingly helpful!

[@RoughTake]

Great video. This is one area a lot of people overlook in a an overall good security posture. Rerouting, deleting, reflection attacks, tunneling etc; all happen within DNS. A simple but extremely vital part of our more secure and private lives that more people are trying to live.

[@aidanfisher7149]

Would love to see more of these. Great to see the basics gone over in a way that's not dry and mundane.

[@weizenw]

Gosh, I really miss Eli’s IT videos man, this is great content, and honestly, it’s much better than most IT vids out there.

[@pratyushdikshit4610]

One of the best presentations to be recommended to those who are interested in DNS Privacy. Thanks you for @Eli for sharing the concepts along with a few open questions

[@xenstarnetwork5333]

Hi, Eli, Thanks a lot for explaining. Due to lockdown since last year, I was bored, and start researching about privacy and security more. I learned a lot from your videos. Also added it on my blog site, so more people will benefit from your videos.

[@DaryushHorshovsky]

Eli have the gift to give deep and professional explanation to complicated issues in simple way.

[@goks1987]

Dude, you are now re-born. Really happy to see you being the good old Eli whom I used to learn from during my initial days as "Rookie Techie".

[@donnieb390]

I have missed these type of ELI videos! Exciting to see this notification. Looking forward to hopefully this becoming a more regular thing

[@madezra64]

Thank you Eli for uploading tech content again! By the way, I listen to your podcasts all the time. Don't worry, some of us love the snark still!

[@okonkwochukwudalu4610]

I am happy to see you back at teaching ELI. I have learnt a lot since "18 from your videos

[@RabiRoil]

Great content! Eli is weirdly good at explaining stuff

[@boutrostawaifi8969]

I learned stuff today i should've known years ago, Thank you Eli

[@aslannoah9835]

So nice to seeing you get back to Computer stuff again. Your old videos started me off when I got interested in networking

[@astroboom8049]

yeahhhh the good all DNS, back to classes with Eli as in the old days, thanks Eli

[@vader11100]

Been since 2008 I use to watch all the videos. I am glad u back again

[@zoowii1813]

How come 2008

[@Error_404-F.cks_Not_Found]

This is fantastic! Great to see the old Eli again. Looks like you just needed a change.

[@brianmlambo3306]

Finally Eli is back making Tech Videos we subscribed for.

[@muratdemirturk2847]

I agree 2000%

[@nosyajdi1910]

Thank you Mr. Eli, hope to see IoT contents as well. This is very helpful for those subscribers outside N.C. and overseas.

[@faris928]

Thank you Eli Where i was learning network basis you were doing a lot of videos When I start learning cyber security You started again your teaching Really awesome thank a lot

[@jaamacdagaale5145]

Eli knows how to best describe things about IT, thank you for your clear defination

[@allenmiller6487]

Eli! Thank you for putting this up!! Good to see you ! ! ! !

[@riezexeero7392]

Good to see your back with these trainings. Keep it up!

[@damospearzo1032]

FINALLY !!!! No more whinging and whining about KZbin, people not watching your videos, or just time wasting videos. This video was fantastic, extremely informative, interesting, with great easy to follow explanations. I learnt more in this 1 + hour video on DNS and security than i did in my paid for course, Cert 4 in computer systems. I am loving seeing you back are doing what you do best, making good solid informative IT videos. Please keep them coming. THE REAL ELI IS BACK !!!!!

[@videojubran]

Good webinar Eli and waiting for more like this

[@amakaamaka3959]

more grace sir....i have been learning from u for the past 10yrs

[@keithpeters586]

The part about getting the dns from the .com .it .tech ..etc. Is not really mentioned in other videos. Good job Eli! This is something I will use just to train and fill the dns entries for a month or two. Probably using a VPN to the authoritative servers. Then switch it to normal dns using cloud-flare, after I think I hit enough of the websites. DNS is usually where I see security fails. Wildly.. understated.. as something you NEED to do for security! Or use a VPN with good DNS and no DNS leaks. But hell ya! Love to get that from the actual source.. I'll be doing that soon!

[@lawrencewilliams6893]

Your videos are really educative Eli, you such an amazing teacher hope i have you in person as a teacher. i have studied cybersecurity and have gotten a certification but still paranoid in finding a job. i'm wanting to watch more videos before meeting an interviewer cuz some are crazy....

[@SuperHtownswag]

eli is an extraordinary teacher. He's the one that introduced myself and others from urban communities to linux and other technologies

[@Wastelander1972]

Good to see you again, Eli. Been a watcher since 2012.

[@efathi2842]

Very happy to see you back educating us again

[@peterstanczak3130]

Thank you Eli, as always fantastic work!!

[@bobleeswagger9294]

Thank you so much for this video ! (I think your community like's seeing you go back to basics:))

[@kyeviramonfariasgentil2415]

Love you Eli!!! I'm happy to see you back.

[@jh61]

I linked a few of your videos to some of the guys who are trying to setup "Do it yourself" IP cams and running into basic networking roadblocks....subnets, DNS, etc. etc..

[@samimkazi1608]

Want your more tutorial on IT as you did before.

[@SavageScientist]

Man im happy to see you are back to doing videos like this

[@ummahofprophetpbuh]

Eli we need more tech videos... ♥️

[@realMattGavin]

Great content btw. I'll finish the silicon dojo playlist while I'm doing my run. I use cloudfare as my DNS to get fast and cheaper service for small town website I run.

[@nithinrkan]

This was the perfect content I needed to understand the concet clearly. Thanks a lot mate. You are awesome teacher.

[@jorgeortega1486]

You have been missed Señor Eli. Great as always.

[@clarkmakoni905]

Eli😁😁😁 Real IT returns to KZbin. Welcome back good Sir. Blessings to you.

[@dogburrito]

This was awesome. When I'm in Asheville I'm gonna' buy you a beer.

[@Martin10thst]

Thank you. Welcome back.

[@brandonmohammed5715]

Back to basics and why worked on KZbin good for you Eli one engineer to another

[@luism.castillo359]

Well come back , Eli as Always an Excelent Teacher

[@crimestoppers1877]

Excellent! Polished.

[@kayombo1001]

Back to the game my big teacher, get greetings from Africa, Angola.

[@WatchfulListener]

Eli: you are way to good for youtube. Please continue with your videos, trust me, the REAL followers appreciate your videos a lot.

[@mgabriel650]

This is next step I love it. Keep it up we need it.

[@Dan-ro6nj]

Would definitely come over if I lived in Asheville.. Eli seems knowledgeable enough to be able to teach the real tech as well, like graphics cards..

[@tamararidi2075]

Thank you very much for the video. It is really clear and helpful.

[@tylercoombs1]

hahahha "If you don't want your ISP tracking you, you can use Google DNS" He couldn't even say it with a straight face. Great, honest video. Appreciate it.

[@genlucero2974]

Great tutorial as usual. Thanks Eli !

[@javadkhazaei1287]

سلام خوش حال شدیم از دیدن شما شما شما ........ thanks a lot......

[@YaBoiRexX]

Eli, did you delete all your non tech videos? Honestly, I'm a pizza delivery guy, and those videos help me get through a lot of my shifts. I think you did the right thing. Much respect. That must've been hard. But I see you're focused and all into silicon dojo. Don't listen to these haters. Even if you don't make as much money as you'd prefer, I'm sure you'll still be quite successful with this endeavor. I would love to come visit one day. Love from nyc.

[@oneGooWorld]

Thank you for the reminder about OpenDNS.

[@tusharwalunj294]

Great to see you back.

[@garcand]

Kickin it old school with new concepts ! Nice!

[@rohanofelvenpower5566]

great lecture, thank you Eli!

[@probowie]

Nice video. Using Pi-Hole with Upstream DNS configured to use OpenDNS. Best I can do for family. Also keeping track of the individual computer's DNS settings (Dad has to have access anytime he wants or Kids get cut off)

[@billyshoffner527]

Thank you Eli keep up the great work sir!

[@ahmeddahmane3879]

I love you so much Mr. Eli, you helped me and learned me seince i was bigenner, thank you

[@brandonfarfan1978]

Good video. This whole thing is really informative to watch. Thanks.

[@mattpgarcia]

Hell yeah! Thank you sir Eli 👍🙏

[@readypubggo5650]

Thanks for making the content easy, and for teaching us with fun... Love from India....

[@joshuablanchette878]

THis is great, really well explained

[@Av-tz4cf]

Thanks, Eli!

[@Weirlive]

thought the Eli guy wasn't making YT videos any more? happy to see him back.

[@DaasaNuDaas]

You are amazing man and you are doing good humanitarian work by teaching us these all sir

[@DumbinhoBM]

That feeling of windows server 2012 active directory videos.

[@GamerAgent24]

Bro. I was just thinking of that as I started this video.

[@shamusobi2748]

Yes yes yes...THIS! Love this! Liked!

[@chuckobra]

Thanks for this, Eli!

[@railpressureflip]

HOLY SHIT YES! So happy you're back!!!

[@catman3661]

Thank you man, after this I changed my router DNS from cloudfare's private DNS and now I can access porn without using vpn and more.

[@anthonyaquino128]

its been a long time since Eli released a video like this

[@maximusdecimus2350]

Great video, simple yet informative explanation. Thank you for sharing your knowledge good Sir.

[@maximusdecimus2350]

P.S. I don't trust TOR either, information out there as to why not to trust this service completely. Opinion backed by data which is why I feel comfortable saying this outloud. Haha

[@mahamatyoussoufdjimet7186]

We miss u, sir. And if possible make Digital Forensics course, please. God bless u.

[@OlaoluwaJolayemi]

Thank you, Eli

[@douglasrobinson8491]

Eli I think I have that exact Hisense TV... I have a question.... On mine, it seems to tilt backwards slightly. Does yours do this? even on the floor, ruling out the desk being uneven...

[@kifni41]

Eli is back. Spotted this video on my feed with 45K views.

[@mrgamer-lu1im]

Nice to see you again eli. Comment here if i get this right this is my own opinion. Dns is a server that takes a dns query and gives you back the ip address of that host or domain name or it resolves the ip address of that domain name or hostname. we can use wireshark and see how dns works. if we use the c programming language or any low level languages and we need to get to like google.com we need to resolve the ip address in order to connect to it through sockets.

[@DavidKing-wk1ws]

Ok, ok so far i got DNS "Do Not eat at Subway" and Cybersecurity is that ding dong sound you hear when walking thru the door :) I really like these videos it looks like the finger painting board they lets us use if we are good and take our meds :)

[@jonp9511]

Depending on your sector, there are some free state sponsored services for reverse DNS. Sometimes even the small business sector can take advantage of as overall community focused security has inherent value.

[@ZachMalmgren]

Don't forget that the PC will look to its DNS cache *before* looking to the HOSTS file.

[@papijelly]

Love it , thanks alot sensei , OSS !

[@Pavulon9001]

Great info, thank you!

[@abdulabouadam2287]

Welcome back . We always ask where is this guy

[@arashaadd]

Captivated the entire video!
