AS4758: the NICNET-VSNL-BOARDER-AP National Informatics Centre network

AS4758 is an internet Autonomous System operated by NICNET-VSNL-BOARDER-AP National Informatics Centre (India). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS4758?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4758 was assigned to NICNET-VSNL-BOARDER-AP National Informatics Centre by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS4758 currently announces 46 IPv4 block(s), totaling about 71.9 thousand addresses (71,936 in all), registered in India. Services from NICNET-VSNL-BOARDER-AP National Informatics Centre are reached through these addresses.

What it means to see AS4758 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4758. That means the other end sits on the NICNET-VSNL-BOARDER-AP National Informatics Centre network (India). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
