I only just now saw this post, the last month i have already been going all out to learn everything that i need for my Security+ (then CySec+) i have a 30hr video course im part way thorugh, and ive set up a few VMs with various servers like OWASP Security Shepherd and Dam Vunurable Web App for some more hands on experience as well as testing on my personal production Nextcloud and Jellyfin servers and ive been having alot of fun with it all, i think im pretty solid with DHCP and subnetting already through my home networking adventures. I will look into each of those other Certs and each thing you mention to learn thank you! Ive been deep into various Linux systems since about 2008 and im hoping to leverage that as much as i can(although its left me with a lack of modern Windows experience).

Thank you so much for all the tips! I feel some good things coming as im getting into this as work.

I left my job as a network engineer to do DDI and it's been a blast. A lot more to DNS than I could have imagined.

Also, a cat explains DNS.
