Announced prefix: 46.166.151.0/24
Announcing ASN: AS43350
Operator: NFORCE

Anycast detection

This appears to be an anycast IP. Reverse DNS returned zero hostnames, the announced prefix is /24 — a routing block large enough to share globally — and the announcing ASN (AS43350) peers with 35 other networks (above the 10-peer floor for a well-connected anycast operator). Many physical hosts can therefore answer for this address from different locations. Learn more about anycast →
