Datatypes

Fully qualified domain name (FQDN)

ID fqdn

DatatypeNot PIIidentifier

Complete domain name of a host or zone, written as labels separated by dots from the host up to the top-level domain, such as www.example.com. A trailing dot stands for the DNS root and is left out in most data. Each label has 1 to 63 letters, digits or hyphens and does not start or end with a hyphen, and the whole name has at most 253 characters (RFC 1035, RFC 1123). Internationalized names are stored as Punycode labels that start with xn--. The regexp requires at least two labels and rejects an all-numeric last label, so IPv4 addresses do not match.
