What is AS13280?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS13280 was assigned to H3G by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS13280 currently announces 24 IPv4 block(s), totaling about 154.9 thousand addresses (154,880 in all), registered in Ireland. Services from H3G are reached through these addresses.
What it means to see AS13280 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS13280. That means the other end sits on the H3G network (Ireland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
