71.18.162.246
IP 71.18.162.246 was identified as a low-risk asset owned by Bytedance Inc. (ASN 11983) within the 71.18.0.0/16 CIDR block. The address operated as a web server presenting a TLS certificate for tiktokcdn.com over HTTP and HTTPS ports. Threat indicators indicated the host was not a known attacker, spam source, or Tor exit node.
However, the profile contained signal contradictions requiring attention. Geolocation data listed the United States, yet RTT measurements recorded a 55ms response time against a minimum possible 126.6ms for the claimed distance. Additionally, the host appeared on one DNSBL in control plane metrics despite a zero blacklist count in primary threat data. The neighborhood classification remained clean with zero abuse density.
Due to these data integrity issues and the presence of signal contradictions, the recommended action was to monitor the address for changes. No active malicious behavior was observed between August 30 and September 10, 2026.
