Traceroute Explained | Real World Examples

[@Mark-n4c9t]

Excellent explanation and visuals. As a lecturer in IT (infrastructure, Cybersecurity) I will be using your video content in lecture classes. Appreciate the uploads!

[@Certbros]

Thanks Mark! Great to hear you liked the video, especially as a lecturer yourself. I hope your classes get some value from it.

[@robinhood8302]

Never have I regretted subscribing to this channel

[@Certbros]

Great to hear! Love having you as a subscriber!

[@9ight5ox]

right ?!!!

[@Don-Carillo]

Always know I'm in for a treat when certbros drops in my notifications. Never dissapointed

[@Certbros]

I'm always in for a treat when Don Neto comments 😁 Thanks man, really appreciate it!

[@Don-Carillo]

@@Certbros haha no problem at all 😊

[@vlya1533]

traceroute and ping are good as base tools for quick diagnostics and network troubleshooting. In addition it's good to note that other tools (like mtr for example) and wrappers can be used to get more stats, info (like whois ASN, registry, ..), graphs, etc.

[@joystickdinosaur]

You are a very good teacher and your videos are very much appreciated. Thank you!

[@superkr1000]

Im a beginner, and DAAAAMN, this is a comprehensive video for dummies like me.

[@86hemantkhare]

great explanation... thanks a lot for clear graphical representation.

[@lieutenant-llama6950]

Please do a video on all the ways you can use NS lookup. Explaining all the various DNS record types would be a good one too.

[@ReflexRL]

CertBros never disappoints. 🙌🏼💯

[@parveezchoudhari7123]

Very nicely explained. Thanks 😊

[@Certbros]

Thank you Parveez! Glad you liked it 👍

[@xeridea]

IIRC, traceroute wasn't designed into networks and the internet, but someone clever figured out you could use the TTL value to find the hops.

[@shadowrealm8937]

great visualization, what tool you used to create it?

[@amarjeetkumarsingh8555]

Easy and detailed explanation.

[@built4u2]

Great job, we’ll spoken!

[@lalith_kumar_akhila2411]

Great explanation

[@Certbros]

Thanks Lalith! Always one of the first people to comment 🙏

[@sovandarason9324]

good explanation and clearly understood .

[@rockinron5113]

Nice one. Clearly explained. Thanks. 😁

[@bhaskarp6722]

Thank you, it was very nice explanation. I got one doubt, I understand that TTL value increases each time, and it sends, and we continue getting Time exceeded value, Type(11), what would be the reply, when it reaches destination.

[@recklessvelociraptor2579]

Can you please tell what tool you used to create the animation?

[@avinashgawade822]

excellent explanation sir.

[@silvanabongiorno3292]

I have a question, I hope you can read it. Would you suggest the installation of wireshark, even if you are not troubleshooting any end users, only for private reasons?

[@milesdyson5211]

QUESTION : Is it ROOT or RRRR-OUT as in Route?

[@silvanabongiorno3292]

Thank you for this tutorial.

[@roneezy5]

Did the tracert crap out because you used a private scope that wasn't a part of your network?

[@fchas15]

excellent! love your channel. thank you!

[@germancalderon1672]

Thank you!

[@Certbros]

You're welcome!

[@ierosgr]

Nice video as always, Near the end where you mentioned that a hop might have a big response time (like 500ms) and we would know that the specific hop causes delay problems, what then? How you bypass that node / hop afterwards? Do you just find out to whom this hop belongs to and send an email letting them know for instance?

[@andresv8856]

I really want to see this question answer .

[@midnitefreakin]

Me too.

[@sajeshk8489]

Very well explained 👏 👌

[@Certbros]

Thank you Sajesh! Glad you liked it.

[@scottcampbell5536]

Please note ICMP is blocked by many switches so ping and traceroute work intermittently.

[@sreejishnair5922]

Great tutorial, can you post video on how to perform port mirroring in Windows Also please make video about ICMP and how ping is a portless protocol I would also request you to make video on Port Binding and socket creation I really want to study this topics from you. Appreciate your efforts

[@killyrodriguez3944]

Cool vid. Very informative 👍

[@Martin958]

Is it possible to use this technology to see what hardware is sending data to your computer? eg. screen capture hardware sending data packets, or can that kind of specificity not be attained?

[@evansonmugo4469]

a very good explanation

[@PetrPekarovic]

great explanation thanks for this video

[@rishimondal3010]

Is there any API to identify the source and destination?

[@baharehshahpar8674]

Awsome explanation

[@roeshambo]

I never realized how painful it was to hear someone say "rooter" Lol.

[@Certbros]

Not as painful as it is to pronounce it r-out-er 😆

[@markfalina9160]

I ran a tracert and received several asterisks (and "request timed out" messages) for many hops. Then one subsequent hop showed times. Afterwards, all remaining hops (limit = 30) showed asterisks and timed out messages. What message should be inferred?

[@saisumanth-ju7xw]

May I know why tracert cmd was taking max of 30 hops?

[@ciscobatais6530]

excellent video keep it up👍

[@eyecatcheramit]

Have used tracert all my life, only learned the mechanism now 😂😂

[@jayrajnaik5117]

As you said "e.g. if the hop is taking around 500ms to respond is potentially bottle naking the traffic." Is there any specific limit of time to ensure that? Thanks

[@xeridea]

First hop may high depending on your internet speed, though most likely less than about 60ms, unless you are saturating your connection. Certain other hops may be high if server is on another continent, and traveling under the ocean but still under 200ms (wild guess).

[@incredibledews66]

I tried to filter wireshark using icmp after typing trace route command in both command prompt and linux , but i did not see any results, can you help me resolve the issue

[@behzadbazargan]

Very Nice , Good learn

[@marlymutos1000]

Thanks for the knowledge

[@camilotello3296]

I loved this video.

[@humairafasihahmed1754]

why are there 3 packets sent tho

[@ludzo2347]

I can see a lot of "request timed out" in your examples, so I was wondering what would be the potentials reasons why a hop doesn't respond to an icmp with expired ttl ?

[@fyzzlefry]

some hops can have icmp disabled but will still pass traffic

[@silvanabongiorno3292]

👍
