isp residential lithuania cable

The AS handle CSC-TELECOM- is held by CSC Telecom, UAB.

What it's used for

  • The address space carries customer traffic, evidenced by netnames such as CSC-Telecom-LT-Customers-85-255 and CSC-Telecom-LT-Customers-193-219.
  • Reverse DNS entries consistently use the csc.lt domain, with patterns like 85-255-97-x.csc.lt indicating dynamic or customer-assigned addresses.
  • With 9,472 IPv4 addresses announced across 14 prefixes and 10 observed neighbours, the ratio suggests an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP data align with the announcer, listing CSC Telecom, UAB or CSC Telecom NOC as the responsible parties.
  • The address inventory is subdivided into multiple /22 and /23 blocks, primarily in the 85.255.0.0/16 and 178.236.0.0/16 ranges, reflecting a structured allocation for customer services.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 436 networks and 1,771 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.
