Summary

German National Tourist Board

Germany · AI-generated

government tourism business

GNTB is the autonomous system for Deutsche Zentrale fur Tourismus e.V. DZT, the German National Tourist Board.

What it's used for

  • The space carries the official digital presence of the German tourism authority, with the netname DE-DZT-20141121 and registrant GNTB Hostmaster; Deutsche Zentrale fur Tourismus e.V. DZT.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of web services, API endpoints, and internal office communications for the national marketing organisation that promotes German tourism abroad on behalf of the federal government.

Notable

  • The registrant data in RDAP aligns perfectly with the AS holder, listing GNTB Hostmaster and Deutsche Zentrale fur Tourismus e.V. DZT for the primary prefix.
  • The address inventory is compact, consisting of a single /22 IPv4 block and two IPv6 prefixes, typical for a government agency with a limited but stable infrastructure footprint.

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 1,783 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.
