Testar grátis 14 dias →AS1640 is an internet Autonomous System operated by TGTEL (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS1640?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS1640 was assigned to TGTEL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS1640 currently announces 7 IPv4 block(s), totaling about 24.6 thousand addresses (24,576 in all), registered in the United States. Services from TGTEL are reached through these addresses.
What it means to see AS1640 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS1640. That means the other end sits on the TGTEL network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
How to see every connection and network your devices reach
Tracing one connection's ASN at a time is tedious. Sentinela, by PC Monitor, maps the devices on your network, shows what is exposed to the internet and helps flag suspicious connections and devices — running on your Windows. Meet Sentinela.
