hosting ucoz cyprus web

COMPUBYTE-AS is operated by Compubyte Limited.

What it's used for

  • The address space carries web hosting infrastructure for the UCoz platform, evidenced by netnames UCOZ-NET and COMPUBYTE-NET and reverse DNS entries such as dev.ucoz.net, s772.ucoz.net, and s40.uid.me.
  • The AS announces 1536 IPv4 addresses across 4 prefixes with 4 observed neighbours, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web server endpoints and development infrastructure supporting the UCoz website builder service.

Notable

  • All registrants for the announced prefixes are Compubyte Limited, matching the AS holder.
  • The address inventory is compact, consisting of two /23 blocks and two /24 blocks, all located in Cyprus.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
