hosting vps cloud uk

FIRSTBYTE-AS is operated by First Server Limited.

What it's used for

  • The address space carries virtual server infrastructure, evidenced by reverse DNS entries such as vm3206859.firstbyte.club and vm4691129.firstbyte.club, alongside netnames like VG-ANDWASE-20190822 and AE-IPMARKET-20140603.
  • The AS announces 16,384 IPv4 addresses across 32 prefixes and 11 IPv6 prefixes, maintaining a single observed neighbour in RIS, which indicates a hosting or cloud provider role rather than transit.
  • Traffic from this AS consists of VPS and cloud hosting endpoints, consistent with FirstByte's business model of providing virtual servers, cloud hosting, and domain services.

Notable

  • Registrants include NETROLE (Andwase Limited), IP MARKET - FZCO, and GeniusMind S.A., indicating that a portion of the announced space is leased or originated by third parties rather than owned directly by First Server Limited.
  • The address inventory is fragmented across multiple /22 and /23 blocks, with some prefixes registered to different entities, reflecting a mixed ownership structure typical of hosting providers that aggregate IP space from various sources.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
