Summary

oh22systems GmbH

Germany · AI-generated

business germany static

The AS handle OH22-AS is held by oh22systems GmbH.

What it's used for

  • The address space carries static IP addresses for the operator's own infrastructure, as indicated by reverse DNS entries such as ip-198-128.static.oh22.net and static-ip-199-126.oh22.net.
  • The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, suggesting a small-scale business or internal corporate network rather than a large access or transit provider.

Notable

  • Registrants for both announced prefixes are consistent with the announcer, listing oh22systems GmbH as the registrant for netnames DE-OH22-20140228 and OH22-NET.
  • The address inventory consists of two distinct IPv4 blocks, 185.49.76.0/22 and 195.137.198.0/23, along with a single IPv6 prefix 2a01:9fa0::/32.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
