Summary

Team Internet

United Kingdom · AI-generated

registry business dns

CENTRALNIC is operated by CentralNic Ltd, now known as Team Internet.

What it's used for

  • The address space carries registry infrastructure, indicated by the netname CENTRALNIC-South-20150401 and registrant CentralNic Network Operations.
  • The AS announces 256 IPv4 addresses in a single /24 prefix and one IPv6 /48 prefix, with only one observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints for the company's registry and DNS services, not subscriber or customer traffic.

Notable

  • The registrant CentralNic Network Operations aligns with the announcer CENTRALNIC.
  • CentralNic Group plc rebranded as Team Internet Group in September 2023.
  • The inventory is a single contiguous IPv4 block and one IPv6 prefix, typical of a corporate internal estate.

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 1,778 prefixes, as published 2026-10-20. 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.
