: How do I optimize the DNS SOA Intervals & TTLs for my site? I am not sure if the DNS SOA Values & TTLs for our Records are optimal or not or even how to determine what is optimal.

I am not sure if the DNS SOA Values & TTLs for our Records are optimal or not or even how to determine what is optimal. My hosting provider has recommended values only. Here are my current settings. So how do you determine what values are best for your website?

DNS Zone:
Refresh: 7200
Retry: 2048
Expire: 1048576
Minimum: 21600

DNS Records:
example.com A - 600
staging.example.com A - 3600
ipv4.example.com A - 43200
ftp.example.com CNAME -43200
sm.example.com CNAME - 43200
lg.example.com CNAME - 43200
example.com CNAME - 43200
example.com MX - 43200

You probably should not worry too much about these things, as long as you are within the safety provided limits you can find on many sites or testing tools such as zonemaster.net/
retry and expire for example would only make sense to your current DNS hoster, they will depend a lot on its infrastructure and the way its nameservers are configured and running.
