Summary

Telco Pro Services

Czechia · AI-generated

transit isp czech regional

TPS-AS is operated by Telco Pro Services, a. s.

What it's used for

  • The address space carries customer and partner infrastructure, evidenced by netnames CZ-TELCOPROSERVICES-20060425, POWERNET-CZ, and CEZNET, along with reverse DNS entries such as proxy-hdt.inplus.cz and cust.tanet.cz.
  • The AS announces 18,688 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, while maintaining 31 observed neighbours; this ratio of moderate address space to high peering density indicates a regional transit and interconnection role.
  • Traffic from this AS consists of regional internet service provider backhaul, enterprise customer connectivity, and transit for smaller Czech networks.

Notable

  • Registrants for the largest prefixes are Telco Pro Services, a. s. and CEZNET s.r.o., with the latter indicating a specific customer or partner allocation within the announced space.
  • The address inventory is composed of three distinct IPv4 blocks, including a /18, a /21, and a /24, alongside two IPv6 prefixes.

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 1,773 prefixes, as published 2026-10-13. 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.
