172.110.223.34 has a threat confidence score of 85%. This IP address from Hong Kong (AS23470, ReliableSite.Net LLC) has been observed in 28 honeypot sessions targeting SIP protocols. First observed on March 22, 2026, most recently active March 23, 2026.
Represents an unsolicited SIP INVITE request targeting a long numeric destination, with the request accepted for processing by the SIP server (100 Trying). While the Call-ID format appears consistent with legitimate SIP implementations, the absence of prior registration and the use of a PSTN-style numeric target indicate probing of call routing or gateway behavior rather than normal call setup. This behavior is commonly observed during early-stage toll-fraud reconnaissance or PBX routing validation.
