hosting leased czech ipv4

The AS handle RELIABLE-COMMUNICATIONS is held by Reliable Communications s.r.o.

What it's used for

  • The address space carries leased or marketplace inventory, evidenced by netnames such as InterLIR-Marketplace and Customer across multiple /23 blocks, alongside a single block registered to RCS Technologies FZE LLC.
  • The AS announces 13,056 IPv4 addresses across 25 prefixes while maintaining only 2 observed neighbours, a ratio that indicates a hosting or aggregation role rather than a transit provider.
  • Traffic from this AS consists of hosted services and customer endpoints, given the operator's business in IT security and custom solutions.

Notable

  • Registrants do not uniformly agree with the announcer; the largest prefix 89.125.132.0/22 is registered to RCS Technologies FZE LLC, while the majority of other prefixes list Abuse contact role object as the registrant with netnames indicating marketplace or customer status.
  • The address inventory is fragmented into numerous /23 and /24 blocks across multiple distinct ranges, including 78.17.x.x, 89.125.x.x, 162.35.x.x, 167.17.x.x, 194.87.x.x, 206.245.x.x, and 13.143.x.x, suggesting a collection of acquired or leased spaces rather than a single contiguous allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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: 446 networks and 1,852 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.
