All-in-one IPv4 / IPv6 Address Lookup

AS54607 (Apogee Telecom Inc.) manages the 64.189.192.0/20 prefix block (approximately 4096 addresses) in the ISP Network category. AS54607 independently controls its routing policy, peering relationships and IP allocation — Apogee Telecom Inc. is directly responsible for traffic to and from addresses in the 64.189.192.0/20 block. The IP 64.189.205.100 resides in United States Texas Fort Worth (timezone America/Chicago); its position within this block determines routing behavior and connectivity characteristics.

The reverse DNS record resolves to 100.205.dhcp.apogeetelecom.com, which is consistent with the registered provider. This alignment with the registered provider is favorable for email deliverability and system trust scores.

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: 64.189.205.100 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.
