Recently I learned: CNAMES come at a cost, esp. if latency to the nameservers are high.

Cloudns.net isn't very expensive for a good anycast DNS service with features like GeoIP.

You can also create ns0/1/2/3.metalhead.club records for their server IPs and use those as the nameservers for metalhead.club and then you skip one more lookup since the nameserver IPs will be included (as glue records) in the lookup for metalhead.club

That's good to know! Thank you! I fact I've already considered ClouDNS. Maybe I'll use their service in the future. Just need to make sure that they use 100 % green energy and their service can be afforded given the donations for metalhead.club.
