Speaking of IT upgrades, this is super impromptu but I decided to fix my local domain situation. When I originally setup my network I didn't really know any better but each server got it's own domain, so appserver.loc, mailserver.loc, firewall.loc etc... I had recently read that you should use appserver.home.arpa, firewall.home.arpa etc... essentially everything is a subdomain under one domain. Another option is a subdomain off a real domain you own so that's what I did. appserver.int.myonlinedomain.com etc. So my internal domain is int.myonlinedomain.com.
All this is way longer to type than .loc though.... but it's a better convention. Also it allows me to use letsencrypt SSL certs locally, since I can validate them. On my public facing DNS server *.int.myonlinedomain.com is a wildcard and just goes to a default holding page on my web server which is where the cert validation script runs. This allows me to get a letsencrypt cert for anything at that domain level, and it will work on my internal network. This is going to stop all the annoying browser warnings for local stuff.
Actually weirdly excited about this new change lol.
Getting a -48vdc power plant setup, now a cleaner domain setup... my network is finally getting some TLC.
