isp hosting business

A German ISP with sixteen IPv4 prefixes, 121 neighbours, and reverse names that say unassigned out loud.

What it's used for

  • Business connectivity and hosting. 12,288 addresses in sixteen IPv4 prefixes, two IPv6 /32s, and 121 observed BGP neighbours.

Notable

  • The company's own blocks share netname DE-ILK-990505, dated YYMMDD, while the newer ones read DE-ILK-20160428 and DE-ILK-20170308 in YYYYMMDD.
  • Several announced blocks belong to other parties: BDSNET to a software consultancy, JMNET to an individual, CAS-DE to InterConnect GmbH, DE-AUDIUS-20210712 to audius GmbH.
  • 194.121.203.0/24 is netname US-GTTCOMMUNICATIONS-19950731, registrant AS3257 Net Admin.
  • Of eighteen sampled addresses, all eighteen answered. Six replied unassigned, four are generated host-N names, and two are broadcast addresses labelled bc..
  • Customer domains show through in the reverse tree: vlb-203-254.schwabe.de and bc.felger.de.

Interesting

  • Publishing unassigned as a reverse name is a positive statement where most networks would publish nothing. The zone is complete enough that empty addresses have an entry saying they are empty, which is the work of somebody maintaining the file rather than generating it.
  • The netname dates are the company's own timeline in two formats. 990505 was written before the year 2000 problem taught everyone to spell years out; the 2016 and 2017 records were written after.
  • 121 neighbours on 12,288 addresses is a network that peers far beyond its size, which is what surviving German regional ISPs did instead of growing.

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.
