Location, ISP, ASN, timezone and coordinates for 2620:fe::fe.
This is Quad9 (United States California Berkeley, AS19281), a well-known public DNS server.
Traffic from this address is routine DNS infrastructure queries — site operators need not block it. However, if this IP appears as an email sender, treat with high suspicion: public DNS servers do not send mail, and a match indicates spoofing or misconfiguration.
Independent offline databases (ip2region vs GeoLite2) may disagree on an IP's location; both are third-party judgments for reference only. The page's primary location prefers ip2region.
Data source: ip2region+GeoLite2 (local offline databases)

Deep Analysis
AS19281 (Quad9) manages the 2620:fe::/48 prefix block (approximately 1.52587890625E-5 addresses) in the Other category. AS19281 independently controls its routing policy, peering relationships and IP allocation — Quad9 is directly responsible for traffic to and from addresses in the 2620:fe::/48 block. The IP 2620:fe::fe resides in United States California Berkeley (timezone America/Chicago); its position within this block determines routing behavior and connectivity characteristics.
No reverse DNS (PTR) record is configured, which is common for dynamically assigned or CGNAT'd addresses but limits reverse verification capability. PTR records are commonly used by mail servers and anti-spam systems to validate connecting IPs — their absence can affect deliverability to strict receivers.
Based on local classification and Spamhaus real-time reputation, no blacklist entries detected, no security risk flags detected. The Unknown category indicates this IP is part of normal Other infrastructure and carries low inherent risk. Balance risk-control with normal access patterns: standard rate limiting plus CAPTCHA on sensitive flows.
Recommendation: insufficient data to classify 2620:fe::fe — apply a balanced policy: standard rate limiting, CAPTCHA for sensitive operations, and monitor access logs for anomalies. Reassess as the IP's usage history accumulates in this site's archive.
