What is AS37333?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS37333 was assigned to COMTEL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

AS37333 currently announces 6 IPv4 block(s), totaling about 9.5 thousand addresses (9,472 in all), registered in South Africa. Services from COMTEL are reached through these addresses.
What it means to see AS37333 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS37333. That means the other end sits on the COMTEL network (South Africa). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
