What is AS18450?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS18450 was assigned to WEBNX by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS18450 currently announces 65 IPv4 block(s), totaling about 98.8 thousand addresses (98,816 in all), registered in the United States. Services from WEBNX are reached through these addresses.
What it means to see AS18450 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS18450. That means the other end sits on the WEBNX network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
