AS198401 currently announces 17 IPv4 block(s), totaling about 14.3 thousand addresses (14,336 in all), registered in Poland. Services from GECKONET-AS are reached through these addresses.

What it means to see AS198401 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS198401. That means the other end sits on the GECKONET-AS network (Poland). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
