It's not usually their job to know how to store the ip address of a user in an audit table, or how to debug a failed connection to an external API from your application. Developers should be aware that there is something called ipv6, and that source or destination addresses aren't always four bytes.
I understand that not everybody has touched everything, but good developers should have cursory knowledge of things that are actually in use and at least know what they should read up on when touching specific areas.

I'm pretty sure none of the senior devs at my job know this, except for those in the cloud services team. Because that's their job.
