About this network

APNIC-COLO — an infrastructure ASN belonging to APNIC, the Regional Internet Registry for the Asia-Pacific. It is used for APNIC's colocated and remote facility sites rather than for customers.

What it's used for

• Announcing APNIC's own service infrastructure hosted at remote and colocated sites, including presence at internet exchange points.
• Supporting registry services and measurement infrastructure operated by the organisation.

Notable

• APNIC is one of the five RIRs; it allocates IP addresses and AS numbers throughout the Asia-Pacific region, so it is the very body that hands out numbers like this one.
• The ASN announces only a small block — this is operational infrastructure, not a network selling connectivity.

Interesting

• Registry infrastructure ASNs like this one carry very little traffic but sit at the root of how everything else on the regional internet gets numbered.
