Summary

First Server Limited

United Kingdom · AI-generated

hosting ip-leasing uk

FIRST-SERVER-EUROPE is operated by First Server Limited.

What it's used for

  • The address space carries leased IP blocks, evidenced by netnames such as IPMarket and AE-IPMARKET-20150619 registered to IP MARKET - FZCO, alongside VG-ANDWASE-20190626 registered to Andwase Limited.
  • The AS announces 16,896 IPv4 addresses across 42 prefixes and 3 IPv6 prefixes, with only 2 observed neighbours, indicating a role focused on hosting and IP leasing rather than transit.
  • Reverse DNS entries like vm3406393.firstbyte.club and vm1950382.firstbyte.club suggest the space supports virtual machine hosting services.

Notable

  • Registrants include IP MARKET - FZCO, Andwase Limited, and FIRST SERVER, SOCIEDAD LIMITADA, indicating the AS aggregates space from multiple leasing entities and related corporate structures.
  • The inventory consists of numerous /22 and /23 blocks, reflecting a fragmented address space typical of an IP leasing or hosting provider.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
