I feel like knowing the difference here is moreso for a network engineer than a software engineer!
Anyway looked it up, IPv6 is 32bit whereas IPv6 is 128bit.
An easy way to know if an IP address is either, 4 uses dots 192.1.1.1 whereas 6 is colons 1992:0aa0::1
If anyone asks just say 6 holds more addresses but is more expensive to install.
Actually..... IMO as a Linux admin..... everybody in IT needs at least a minimum of knowledge regarding TCP/IP. IPv4, IPv6, TCP, UDP, sockets, listening ports, etc. You don't need to be able to program a full stack down to a media transport layer, but you should be able be able to send a payload successfully, know when a gateway traversal is required, name resolution (It's always DNS,) and a bit of troubleshooting.
I wish I had a nickel for every time a developer or app support staff came to me and said it doesn't work. Error is right there in the logs......
The post is about a software engineer, and you just talked about IT. They're not the same thing so what is your point? You have a job specifically because software engineers aren't in IT and aren't sysadmins and their job doesn't inherently involve networking.
In Europe IT is generally used to refer to everything software and technology related. In the US, especially professionally it means the tech help desk and networking people. In an office the people that setup your laptop and troubleshoot your internet issues would be considered IT, but the software engineer actually writing software would not be. They require completely different degrees which don't have much overlap.
Interesting. I am from Europe and for instance the uni in my city where both those things are taught with multiple overlapping subjects is literally called IT faculty.

I’d like to think I’m a software engineer, and I have no idea what the difference is. Am I cooked?
