AS9937: the DELTANET-AS-AP Delta Networks network

AS9937 is an internet Autonomous System operated by DELTANET-AS-AP Delta Networks (Pakistan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS9937?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9937 was assigned to DELTANET-AS-AP Delta Networks by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS9937 currently announces 3 IPv4 block(s), totaling about 2.3 thousand addresses (2,304 in all), registered in Pakistan. Services from DELTANET-AS-AP Delta Networks are reached through these addresses.

What it means to see AS9937 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9937. That means the other end sits on the DELTANET-AS-AP Delta Networks network (Pakistan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
