so im setting up my network, and going through alot of options. i enabled dnssec, i enabled dns over tls to cloudflare, and currently i have ipv6 via track interface, i have 10/10 ipv6 on testmy-ipv6, but i was watching youtube configs and im hearing theres a newer way for both ipv4 and ipv6, what steps should i be taking to take advantage of the lastest feature sets?
