You can use whatever nameservers you like as long as you can point the relevant DNS records to the server.

I'm self hosting DNS on the same machines with nsd. Since in this case one of the anycast nodes is a master and the other two are slaves, updating the master from the slaves would require additional w

Huh, this is a pretty clever solution. I would have just gone with DNS verification though (Image)

Any reason you're using HTTP auth and not DNS-based auth (assuming your DNS server has an API of course)

dns TXT record verification get * wildcard (Image)

I've got all the three locations from BuyVM in order to deploy my personal website on the freely provided anycast IP Address both for DNS and HTTP.

Unless you are hosting dns servers at different server location, don’t waste your money or IP (Image)

@Hotmarer what tool is this? I don't get the numbers if you compare dns vs. e.g. ttfb. Does it once check dns lookup and then uses dns cache? Or how come ttfb is lower than dns (e.g. NY on CF)?

godaddy has a domain monitoring service for things shuch as dns changes, status changes, etc; can't recall if that was at their paid (auctions) level or not.

install the required perl dependencies for clatd: cpan net::ip socket6 io::socket::inet6 net::dns.

Does disabling DNS lookups actually save many resources? Are there even libc implementations that don't have getaddrinfo given it's a standard POSIX function?

Ultimately, unless you need NTP (which can also get a harcoded IP), there's many devices which don't otherwise need DNS services and they turn it off to save resources.

Don't these devices usually get their network configuration using DHCP, or SLAAC + RA (RFC5006) for IPv6? If they're using DHCP, that'll provide the DNS server addresses too. If they're not using DHCP

It's usually done so it connects even without DNS configured. But then they hardcore a DNS like Google or the 4.2.2.2's of the world to solve that in a much better way.

IPs rather than owning them) rather than using DNS. I'm not sure why... Even the most basic embedded devices/platforms usually have some sort of DNS client.
