The Tunnel-Client-Endpoint attribute contains the address of the initiator of the tunnel. It’s designed to work in conjunction with the Tunnel-Server-Endpoint and Acct-Tunnel-Connection-ID attributes to provide a way to identify a specific tunnel for accounting, billing, and auditing functions. If the tunnel is an IPv4 tunnel, then the value of this attribute is either the FQDN of the initiator end of the tunnel or the dotted-decimal (x.x.x.x) address of the initiator. If the tunnel is an IPv6 tunnel, the string is either the FQDN as described here or a textual representation of the address. All other tunnel formats use a tag that refers to local configuration data specific to the medium.
