This is Cisco OpenDNS, LLC (United States California, AS36692), 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)
