dns

SRV requires the full service path. Enter the full name, e.g. _http._tcp.example.com or _xmpp-client._tcp.example.com

PTR requires reverse DNS format. Reverse the IP octets and append .in-addr.arpa — e.g. for 1.2.3.4 enter 4.3.2.1.in-addr.arpa

CNAME records live on a subdomain. Enter the full subdomain the alias is on, e.g. www.example.com or blog.example.com — a root domain (example.com) usually can't have a CNAME.
