⚠ 1 MOAS prefix — multiple origin ASNs detected

All MOAS anomalies →

A previously stable prefix originated by AS270 is now also announced by another ASN (MOAS — Multiple-Origin AS), detected from our RIPE RIS collectors. Often benign (anycast, multi-homing, or a recent transfer) — but it can signal a route leak or prefix hijack, so it's worth inspecting.

Frequently Asked Questions

What is AS270?

AS270 is an Autonomous System Number assigned to National Aeronautics and Space Administration. An ASN identifies a network that controls a specific set of IP addresses and determines how traffic is routed across the internet via BGP (Border Gateway Protocol).

How many IP addresses does AS270 announce?

AS270 announces 2.12M IPv4 addresses distributed across 101 routed CIDR prefixes. The network is registered in United States.

Who operates AS270?

AS270 is operated by National Aeronautics and Space Administration. The organization is based in United States. You can view all IP ranges and related ASNs on the organization page.

What country is AS270 registered in?

AS270 is registered in United States. This indicates where the network operator is headquartered, though the IP addresses it announces may serve users globally.
