Default Gateway Explained

What is a default gateway? A default gateway is a device that forwards data from one network to another. And the majority of the time this is going to be a router. This video also explains what is the host and network portion of an IP address.

[@AutomateTopicalAuthority]

I would like to iterate how amazing this channel's videos are... I have about 7 certs and Net+ being one for them. I got it 10 years ago and didn't dabble in networking as much as I wanted to. So, as a refresher, I've gone through more than half the content on this channel even the basic topics, and have learned much more about those topics than I knew when I passed the exam. There is no course I have taken that explains the content the way it is explained in this channel. PLEASE make more courses exactly like this, animated. So easy to understand every single detail, it sticks and I don't have to watch it again or take notes. CCNA, CCNP, CISSP, Pentest+, CASP, any of the intermediate to advanced certs, PLEASE. Take my money!!! If any of those courses were made like this, no other training company would compete.

As a guy who's been a network engineer for 25 years, seeing videos like this is surreal to me. Well done on providing an excellent layman's explanation. I've found that it's difficult to explain these concepts because your average person doesn't understand how the OSI model/layer 2 vs layer 3 networking works.

[@drip888]

i got some questions, its not about this video but a general question. i have a domain and a website is running on the domain which is being executed in VPS. i prefer the database to be in my home, how can i make sure the website gets data from my database to use it.

Thank you so much for clarifying that topic, i have been aware of default gateways and subnet masks for years. But i never understood their purpose. 👍👍👍👍

[@ahmad-murery]

Can't get enough of this channel, I encountered similar situation more than once, but I couldn't access computer B form A until I added a second IP address on computer A that matches the network of computer B, the default gateway device we used was a regular ADSL home router, so not sure whether it 's capable to route packets between different local networks or not, Already excited about your next video, Thanks

[@Cavewalker76]

I think you use two network addresses on the same physical network. That's not going to work as you say. I don't know why you want to use two different network addresses on the same physical network, unless you have more hosts then are available for that subnet. In that case it's better to make one large subnet for those hosts ( If you have two 24 bit subnets then make a 23 bits subnet ( 255.255.254.0 ). Then you have 1024 hosts on your network. When you have a lot of overhead on your network you can isolate both networks physically from each other and connect them together with a router.

[@chaunceeeeyy]

I've always wondered what subnet masks are for as they're 255.255.255.0 on every network. Thank you for videos, you certainly inspire people to learn

[@James_Knott]

No, they are not 255.255.255.0 on every network. That is just a common value for consumer grade routers, but you can use any size that's big enough to contain all the local devices. For example, if you have 10 devices on a LAN, you could use 255.255.255.240, which would allow 16 local address, less 1 for broadcast and 1 for the network, for a total of 14. With NAT addresses, such as used here, subnet size doesn't matter much, as long as it's big enough. However, with public addresses, the mask can only be big enough to contain the addresses that you have been assigned. If you try to use a bigger subnet, you'd be stepping on someone else's address space. Also, get in the habit of using /24, instead of 255.255.255.0, as it makes it easier to figure out how big a subnet is. On IPv6, however, you get absolutely huge subnets. The standard subnet size for a network is a /64, which is 18.4 billion, billion addresses or the entire IPv4 address space squared. I get 256 of those from my ISP and some provide 65536. There are also some cheap ISPs that provide 16 /64s and some downright stingy ones that provide only a single /64.
