AS3856 — PCH-AS

AS3856 announces 1 IPv4 prefixes covering 256 addresses and 1 IPv6 prefixes.

About this network

Packet Clearing House (PCH-AS), the non-profit research institute that supports internet exchange points and critical DNS infrastructure worldwide.

What it's used for

• Operating route collectors and route servers at internet exchange points, and running anycast DNS service used by top-level domains.
• Only 256 IPv4 addresses — a tiny allocation whose importance is wildly out of proportion to its size, because anycast lets the same small block appear in many places at once.

Notable

• This is infrastructure, not an ISP or an enterprise: there are no subscribers behind it. Addresses here are servers that other networks depend on.
• PCH is one of the longest-running sources of public data on internet exchange points and interdomain routing, and its route-collector archives are widely used in research.

Interesting

• Because the prefix is anycast, a traceroute to a PCH address can end in a completely different country depending on where you start — geolocating this ASN to a single place is meaningless by design.
