CGNAT & mobile IP checker

Is an IP behind carrier-grade NAT, or a mobile-carrier address? Enter an IPv4 to check the RFC 6598 range and the owning network. Free, instant, nothing stored.

Checks 100.64.0.0/10 (RFC 6598) plus the owning ASN. No logging.

What is CGNAT?

Carrier-grade NAT lets an ISP put many subscribers behind one public IP. Mobile networks do this almost universally — which is exactly why mobile IPs are so hard to block: thousands of real users share each one, so sites can’t ban it without hurting genuine traffic.

Why that matters for proxies

A dedicated datacenter IP is yours alone, so one bad actor gets it blocked instantly. VeilSocks mobile IPs sit behind real carrier CGNAT shared with ordinary phone users — the blend that keeps them trusted. Dig deeper with what-is-my-IP, ASN lookup or a blacklist check.
