Homework Help / Block diagram as text software...

Last post by networkloser - December 28, 2025, 07:02:45 AM

There are various stuffs for UML like plantUML etc. But what about for network block diagram. Are there anything?
I want to make diagram as code.


For example something like this:

A->B->C

Where A, B and C will be blocks. Request-response cycle will be shown.

i know ipv4 has 32 bits. ipv4 datagram format etc. only. not a lot i can recall.

Start with this information: http://www.tcpipguide.com/free/t_IPSubnetAddressingSubnettingConcepts.htm

Sections linked from the main page, and keep in mind that classless addressing is how we do things. A/B/C networks aren't used like that anymore, thanks to private IP spaces defined in RFC 1918.

start with subnetting, learn to subnet, it is the basis of network layer,  once you can subnet, the network layer will be more understandable.

That's a very broad range. You need to start somewhere. I would pick first IP Addressing, as that is the number one area that everything starts with, and it's IPv4 that's out there for the most part. IPv6 exists, but v4 is still dominant. What you learn for v4 will be handy for v6, so there's that.

What do you already know about v4? From that, we can look at resources for getting that totally covered before going into the other topics.
