AS18155: the BISPIET-AS-AP Bangladesh Internet Service Provider Internet Exchange Trust network

AS18155 is an internet Autonomous System operated by BISPIET-AS-AP Bangladesh Internet Service Provider Internet Exchange Trust (Bangladesh). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS18155?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS18155 was assigned to BISPIET-AS-AP Bangladesh Internet Service Provider Internet Exchange Trust by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS18155 currently announces 1 IPv4 block(s), totaling 256 addresses (256 in all), registered in Bangladesh. Services from BISPIET-AS-AP Bangladesh Internet Service Provider Internet Exchange Trust are reached through these addresses.

What it means to see AS18155 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS18155. That means the other end sits on the BISPIET-AS-AP Bangladesh Internet Service Provider Internet Exchange Trust network (Bangladesh). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
