Summary

CSC Telecom Estonia

Estonia · AI-generated

telecom business estonia

CTE1 is held by CSC Telecom Estonia.

What it's used for

  • The address space carries business telecommunications traffic, evidenced by reverse DNS entries pointing to csc.ee and netnames EE-CSCTELECOM-20100611 and EE-CSCTELECOM-20201111.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a business access network rather than a transit provider.
  • Traffic from this AS consists of business customer communications, including VoIP and data services, as CSC Telecom provides telecommunications solutions to business customers in the Baltic region.

Notable

  • Registrants for both announced prefixes are listed as OU CSC Telecom Estonia, matching the AS holder.
  • CSC Telecom has been operating in the Estonian telecommunications market for over 20 years, providing services to business customers across the Baltic countries.
  • The inventory consists of two /24 blocks, 178.236.203.0/24 and 185.213.44.0/24, with no IPv6 prefixes announced.

Reputation

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.
