Summary

UAB Marsatas

Lithuania · AI-generated

residential isp fiber lt

MARSATAS-LT-AS is operated by UAB Marsatas.

What it's used for

  • The address space carries residential and business internet traffic, evidenced by netnames Marsatas and NTT_MARSATAS_NET and reverse DNS entries like eth-51-255.marsatas.lt.
  • The AS announces 6144 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio indicative of an access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for high-speed fiber internet and smart television services provided in the Marijampolė region.

Notable

  • Registrants for all announced prefixes are consistent with the announcer, listing Marsatas Admin, Marsatas Hostmaster, and UAB Marsatas.
  • The address inventory is composed of four distinct IPv4 blocks, including two /21s and two /22s, with no IPv6 prefixes in the inventory.

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 1,784 prefixes, as published 2026-10-19. 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.
