AOIT is held by Andreas Otto.

What it's used for

  • The space carries a single IPv4 block, 185.5.12.0/23, with netname DE-AOIT-20120928 and registrant Andreas Otto; AOIT ABUSE.
  • The inventory consists of 512 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated network rather than a transit or large access provider.
  • Reverse DNS for 185.5.13.126 resolves to ms3.dionera.com, suggesting the space hosts specific server infrastructure or endpoints associated with that domain.

Notable

  • The RDAP registrant Andreas Otto matches the registry holder and the AS handle AOIT, confirming direct ownership.
  • The address inventory is minimal, comprising a single /23 block and a /30 IPv6 prefix, with no indication of subdivision or large-scale deployment.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
