What an A record is

An A record maps a hostname to an IPv4 address. A domain can have several, and clients pick one. If the record is a CNAME instead, this page shows no A at that name — follow the alias, or use the ALL check.

TTL

The TTL is how many seconds resolvers may cache the answer. A low TTL makes cutovers faster and makes DNS lookups slightly more chatty.
