Summary

Fornex Hosting

Spain · AI-generated

hosting business isp

A block registered this year is labelled as legacy space.

What it's used for

  • A hosting provider. Thirty-three IPv4 prefixes and one IPv6 /47 announced from Spain, nine thousand four hundred and seventy-two addresses, across twenty-nine observed BGP neighbours.

Notable

  • The prefixes are mostly single blocks scattered across many unrelated ranges rather than one contiguous holding, which is what buying address space piece by piece looks like.
  • The AS handle names one country while the announcements come from another, and the netnames use both country codes on different blocks.
  • One netname is the word for legacy, the brand, and a date from this year: recently registered space that the label marks as belonging to an older allocation era.
  • Most blocks list only a coordination role as registrant; a few also name the company.
  • Fifteen of eighteen queried addresses answered, every one a six-digit number on the brand's domain. The numbers are unrelated to the addresses and unrelated to each other.
  • First seen in the routing archive far later than its numeric neighbours.

Interesting

  • Six-digit names that track nothing about the address are customer or machine identifiers straight out of a billing system. They are stable across moves, which is exactly what a hosting provider wants and exactly what makes them useless to anyone outside.
  • Scattered small blocks and a late first sighting together describe a business assembled from transfers rather than grown from an allocation.

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 1,784 prefixes, as published 2026-10-19. 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.
