Summary

Cosmos TV

Belarus · AI-generated

cable dsl isp residential

COSMOSTV-AS is operated by Cosmos TV JLLC, a Belarusian cable and DSL provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as nat-10-pool-1-ip-4.cosmostv.by and user-ip-56.cosmostv.by.
  • With 6,400 IPv4 addresses and 19 IPv6 prefixes announced against only 4 observed neighbours, the network functions as an access provider rather than a transit carrier.

Notable

  • Registrants are consistent with the announcer, primarily listing JCLL "Cosmos TV" and COSMOS TV JLLC, with one prefix registered to Netland ODO under the netname BY-INTERNETSERVICE-20080415.
  • The inventory consists of nine IPv4 prefixes, including a /21 and several /22s and /24s, alongside a set of contiguous IPv6 prefixes in the 2a0a:eac2::/40 range.

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.
