Summary

Tønder Kommune

Denmark · AI-generated

government municipal denmark

The AS handle TK-AS is held by Tønder Kommune.

What it's used for

  • The address space is registered under the netname DK-TOENDER-20170629 with registrant IT drift; Toender Kommune, indicating internal municipal IT infrastructure.
  • The network announces a single IPv4 prefix, 185.210.236.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour, the routing profile suggests a stub or isolated network rather than a transit provider, consistent with a local government entity managing its own connectivity.

Notable

  • The RDAP registrant IT drift; Toender Kommune aligns directly with the AS holder, confirming the space is owned and operated by the municipality itself.
  • The inventory consists of a single contiguous /22 block, representing a modest, self-contained address estate typical of a small administrative body.

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: 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.
