Germany · AI-generated

isp residential germany business

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.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
