AS5650 independently controls its routing policy, peering relationships and IP allocation — Frontier Communications of America, Inc. is directly responsible for traffic to and from addresses in the 47.157.44.0/22 block.

The reverse DNS record resolves to 47-157-47-245.fdr01.wlnt.ca.ip.frontiernet.net, 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: 47.157.47.245 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.
