Summary

Zenex 5ive

United Kingdom · AI-generated

hosting business uk

ZENEX5IVE-US is operated by Zenex 5ive Limited.

What it's used for

  • The address space carries hosting infrastructure, evidenced by the netname IPXO on 151.245.168.0/24 and the registrant Zenex 5ive Limited on 193.109.108.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 1 observed neighbour, a ratio consistent with a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of dedicated server and cloud hosting endpoints, as Zenex 5ive provides high-bandwidth dedicated servers and cloud hosting services.

Notable

  • Registrants align with the announcer for 193.109.108.0/24, while 151.245.168.0/24 is registered to CIO; DIAMOND IP BROKERS FZCO; Internet Utilities Abuse Contact under the netname IPXO, indicating leased or brokered IP space.
  • The inventory consists of two /24 blocks, one of which is associated with IPXO, a major IP brokerage, suggesting a mixed ownership or leasing arrangement for the address space.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
