Summary

Sellwerk

Germany · AI-generated

business enterprise

1,280 IPv4 addresses, a full IPv6 /29, and a reverse zone that names the business model out loud.

What it's used for

  • Corporate connectivity for a directory and digital-marketing group. 1,280 addresses in three IPv4 prefixes, two IPv6 prefixes, and three observed BGP neighbours.

Notable

  • 86.109.248.0/23 is netname IT2MEDIA-NET; 185.76.156.0/24 is DE-IT2MEDIA-20200219.
  • Contacts include ODN Hostmaster and it2media-technik, while the holder is Sellwerk Verwaltungs GmbH.
  • The IPv6 announcements are 2001:67c:14b8::/48, out of the registry's own assignment range, and 2a06:87c0::/29, a full allocation.
  • Sampled addresses answer r2.lead-hub.de, nu.vhm-ibb.de and tb-delivery-1.it2media.de.

Interesting

  • lead-hub is what the company sells, written into a hostname: sales leads, collected and distributed. Marketing infrastructure tends to be named with unusual candour because the people naming it are describing the product to each other rather than to the public, and reverse DNS is the one place that conversation becomes visible.
  • Four unrelated brand names across three blocks and three hostnames, with a fifth on the holder line. Directory businesses are assembled by acquisition, and every acquisition leaves a name somewhere in the record.
  • The address ratio is the modern one turned inside out: 1,280 IPv4 addresses against a /29 of IPv6, an allocation the size a national carrier would receive. One side is rationed and the other is not.

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 1,779 prefixes, as published 2026-10-23. 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.
