About this network

CMO-AS is operated by CMO Internet Dienstleistungen GmbH.

What it's used for

• The address space carries commercial internet service provision in Germany, as indicated by the netnames DE-CMO-20020702 and DE-CMO-20170906 and the registrant identity.
• The AS announces 5120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours. This high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

Notable

• The RDAP registrants for both announced IPv4 prefixes are CMO Internet Dienstleistungen GmbH; Abuse Department, which aligns perfectly with the AS holder.
• The address inventory consists of one /20 block (81.90.32.0/20) and one /22 block (185.219.196.0/22), representing a modest footprint typical of a regional or niche ISP.
