business hosting managed-services it-infrastructure

CONFIGO-AS is operated by Configo Systems Gesellschaft fuer Systemloesungen mbH.

What it's used for

  • The address space carries corporate IT infrastructure and managed services, evidenced by netnames such as CONFIGO-NET and DE-CONFIGO-SYSTEMS-20100507, and a reverse DNS entry asspm.agentur-schnittstelle.com.
  • The AS announces 5632 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining 58 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a business network providing transit and connectivity services rather than a large-scale residential access provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to Configo Systems Gesellschaft fuer Systemloesungen mbH, though 185.222.204.0/22 is registered to Riverland Reply GmbH and 185.237.34.0/24 to Ralf Bender.
  • The address inventory consists of six distinct IPv4 blocks of varying sizes, ranging from a /21 to two /24s, alongside a single /32 IPv6 prefix.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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.
