Summary

Netherlands · AI-generated

hosting business

Six address blocks collected one at a time between 2009 and 2023, totalling 3,072 addresses.

What it's used for

  • Hosting and business connectivity in the Netherlands. 3,072 addresses in six IPv4 prefixes, one IPv6 prefix, and one observed BGP neighbour.

Notable

  • The netnames are NL-ONWORX-20090422, NL-ONWORX-20090529, NL-ONWORX-20160104, NL-ONWORX-20200312, NL-ONWORX-20230612, and one bare NL-ONWORX with no date.
  • Two /22s and four /24s, from five different /8s.
  • The IPv6 announcement is 2a10:7180::/29, out of a range the registry only began issuing recently.
  • The AS handle is AS-XYNTA, unrelated to the holder name Onworx BV.
  • One sampled address of eighteen answered, as whs5.srvnl.nl.

Interesting

  • Fourteen years of address history in six transactions, and the whole collection is 3,072 addresses — less than one of the /19s that a 1999 applicant would have been handed without argument. The dates tell the story of IPv4 after exhaustion: two blocks in 2009 while there was still space, then nothing until 2016, then single /24s bought or waited for.
  • The 2023 entry is the most recent netname date in this stretch of the number range. Networks are still acquiring IPv4, one /24 at a time, at prices the 2009 entries never paid.
  • The AS handle, the holder name and the reverse zone srvnl.nl are three unrelated words. Each was chosen at a different moment by different people, and nothing in the system ever forces them to agree.

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 1,782 prefixes, as published 2026-10-16. 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.
