Location, ISP, ASN, timezone and coordinates for 114.114.115.115.
This is Zenlayer Inc (China Jiangsu Nanjing, AS21859), 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
AS21859 (Zenlayer Inc) manages the 114.114.0.0/16 prefix block (approximately 65536 addresses) in the Datacenter / Cloud category. AS21859 independently controls its routing policy, peering relationships and IP allocation — Zenlayer Inc is directly responsible for traffic to and from addresses in the 114.114.0.0/16 block. The IP 114.114.115.115 resides in China Jiangsu Nanjing (timezone Asia/Shanghai); its position within this block determines routing behavior and connectivity characteristics.
The reverse DNS record resolves to public2.114dns.com, which may reflect a different service layer or hosting configuration. The mismatch between PTR and provider name may cause elevated scrutiny from mail servers and WAFs during reverse verification.
Based on local classification and Spamhaus real-time reputation, no blacklist entries detected, associated risks: datacenter. The Cloud server / datacenter category indicates this IP is part of normal Datacenter / Cloud infrastructure and carries low inherent risk. As a datacenter address, risk-control focus should be on request patterns (user-agent, frequency, behavior chains) rather than the IP alone.
Recommendation: 114.114.115.115 is a datacenter/cloud IP — it may host legitimate services (APIs, CDNs, bots) or serve as an attack vector. Evaluate each request context: allow known API integrations, challenge or block unknown automated traffic, and never trust the client-reported IP for geo-based decisions.
Datacenter IPs are frequently used for legitimate API integrations, automated monitoring and infrastructure tasks — evaluate each request context before blocking. If you need to distinguish automation from real-user traffic, focus on request headers (User-Agent, Accept) and behavioral patterns rather than IP reputation alone.
