Question: What format shall the Provisioning GANC-SEGW identifier take, and what characters are allowed for each label within this format?
Option 1: Fully Qualified Domain Name (FQDN) with labels consisting of alphabetic characters (A-Z and a-z), digits (0-9), and the hyphen (-), starting and ending with an alphabetic character or digit.
Option 2: IP Address with any combination of alphanumeric characters and special characters.
Option 3: Simple Domain Name with labels limited to only alphabetic characters (A-Z and a-z).
Option 4: Numerical Identifier consisting solely of digits (0-9) without any separators.
Explanation: According to the specifications for Provisioning GANC-SEGW identifiers, they must be in the form of a Fully Qualified Domain Name (FQDN), as outlined in IETF RFCs. Each label within this FQDN can contain alphabetic characters (both uppercase and lowercase), digits, and hyphens, with the constraint that each label must begin and end with either an alphabet or a digit, highlighting the importance of precise formatting for network identification and communication.
