string val_Hostname::Validate

(

const string &

a_strVal

)

[virtual]

Host name consists of multiple dot separated identifiers.

Each identifier can be 63 characters long, overall length of FQDN (Fully Qualified Domain Name) must be less than or equal to 255 characters.

Valid characters for a hostname are 'A'-'Z', a-z and -. (RFC 1123)

Reimplemented from val_Value.
