SIP FAQ : SIP Protocol Operation :
How long can SIP host names be? |
| DNS (RFC 1035, Section 3.1) limits labels (each component of a host name) to 63 characters. The total length of a domain name (i.e.,label octets and label length octets) is restricted to 255 octets or less. http://www.networksolutions.com/help/long-domains.html, however, claims that host names can be up to 80 characters long.

| Note, however, that SIP implementations MUST be prepared to handle host names of any length, subject to any maximum message size restrictions that are part of local policy.
