Summary

tbspace

Germany · AI-generated

amateur radio non-profit germany

The AS handle is TBSPACE and the holder is tbspace Networks.

What it's used for

  • The address space carries amateur radio digital communications, evidenced by the netname AMPRNET and registrant Amateur Radio Digital Communications for the announced prefix.
  • The network announces 256 IPv4 addresses and 1 IPv6 prefix, with 30 observed neighbours; this ratio of small address inventory to high peering count indicates a transit or interconnection role rather than a large access network.
  • Traffic from this AS consists of amateur radio digital communications, supporting the non-profit mission of the operator.

Notable

  • The RDAP registrant Amateur Radio Digital Communications differs from the AS holder tbspace, indicating the address space is allocated for specific amateur radio use within the tbspace network.
  • The address inventory is minimal, consisting of a single /24 IPv4 block and a single /48 IPv6 block, consistent with a specialized non-profit operation.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
