AS42708 currently announces 172 IPv4 block(s), totaling about 156.9 thousand addresses (156,928 in all), registered in Sweden. Services from GLESYS glesys.com are reached through these addresses.

What it means to see AS42708 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS42708. That means the other end sits on the GLESYS glesys.com network (Sweden). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
