Summary

XOO Networks Consulting

Germany · AI-generated

consulting business germany small

XOO-AS is operated by XOO Networks Consulting, a German network consultancy.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netnames DE-XOO-20190911, DE-XOO-20190815, and XOO-NET, all registered to Ulf Kieber and Xoo Guardian.
  • With 2816 IPv4 addresses announced across 4 prefixes and only 1 observed neighbour, the network functions as a small, self-contained business estate rather than a transit or access provider.

Notable

  • All registrants in the RDAP data align with the announcer, listing Ulf Kieber, Xoo Guardian, and X O O Abuse Contact for every prefix.
  • The inventory consists of four distinct IPv4 blocks, including two /22s and two smaller prefixes, alongside two IPv6 prefixes, indicating a modest but segmented internal network.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
