Location, ISP, ASN, timezone and coordinates for 101.82.235.245.
This is China Telecom (China Shanghai, AS4812), an ISP broadband address.
Home broadband users are real residential users with high risk-control value, though geolocation accuracy is limited (some regions share CGNAT). Risk-control advice: focus on behavioral anomalies rather than the IP itself.
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
AS4812（China Telecom (Group)） (China Telecom) manages the 101.82.224.0/20 prefix block (approximately 4096 addresses) in the ISP Network category. China Telecom Shanghai node, the main broadband exit in East China. The IP 101.82.235.245 resides in China Shanghai (timezone Asia/Shanghai); 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. Home-broadband and CGNAT addresses commonly lack PTR records; this limits reverse verification but is normal for dynamic residential pools.
As a Home broadband address, it is part of the ISP's dynamic pool — multiple users may share the same external IP over time, and geolocation accuracy is limited to the ISP's registered region rather than the individual subscriber's location. Residential IPs carry high fraud-prevention value but low geolocation precision; prioritize behavioral signals over address reputation.
Recommendation: 101.82.235.245 is a residential IP — prioritize behavioral signals over IP reputation. Monitor for abnormal request velocity, repeated failed logins or automated patterns. Avoid blanket blocking of residential IPs even when Spamhaus lists them (PBL entries are informational, not indicative of abuse).
If you operate a website or service that receives traffic from this IP, note that the same external address may represent multiple different subscribers behind CGNAT. Blocking this IP could unintentionally exclude legitimate users — consider applying rate-limiting per session rather than per-IP.
