Classifies the kind of remote peer this tunnel connects to: a regular fixed-IP gateway, a DAIP, or Dynamically Assigned IP, gateway whose address can change, or a ROBO, Remote Office/Branch Office, gateway. This classification matters because DAIP peers need to be resolved by name or registration rather than a static IP each time they reconnect, so a tunnel flagged daip that keeps failing to re-establish after the peer's ISP-assigned address changes points at a DNS or registration resolution problem rather than a policy or crypto issue. Example: a tunnel to a small branch office correctly reporting tunnelPeerType daip(2) explains why that specific tunnel needs to re-resolve the peer's address on every reconnect, unlike the regular(1) tunnels to fixed data-center peers.
