Authoritative answers can be found from:
example.com    nameserver = ns48.domaincontrol.com.
example.com    nameserver = ns47.domaincontrol.com.
aspmx.l.google.com    internet address = 209.85.222.1
aspmx2.googlemail.com    internet address = 209.85.135.2
aspmx3.googlemail.com    internet address = 209.85.199.2
