Summary

Web4ce

Czechia · AI-generated

hosting web czech

The AS handle WEB4CE is operated by Web4ce, s.r.o.

What it's used for

  • The address space carries web hosting and design services, evidenced by reverse DNS entries such as gate.web4ce.cz and pop-vs1-bbbbk-net.web4ce.cz.
  • The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web hosting endpoints and web design services for clients in the Czech Republic.

Notable

  • Registrants for both announced prefixes are Web4ce, s.r.o., matching the AS holder.
  • The address inventory is compact, consisting of one /21 and one /22 block, typical for a specialized web hosting provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,778 prefixes, as published 2026-10-20. 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.
