INTERNET-6 is operated by Karolio IT paslaugos, UAB, a Lithuanian IT services company based in Klaipėda.

What it's used for

  • The address space carries a mix of netnames including LT-UABKAROLIO for the operator's own blocks and IPXO/NETUTILS for leased transit or peering space from Internet Utilities.
  • With 23,808 IPv4 addresses across 72 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access, consistent with the operator's registration as a Cable/DSL/ISP on PeeringDB.

Notable

  • Registrants for the largest prefixes include Karolio IT paslaugos, UAB, Mantas Berzinis (MB "Serverita"), NTT America, Inc., and Internet Utilities entities, showing a mix of owned and third-party allocated space.
  • The inventory is fragmented into many small /24 and /23 blocks alongside a few /22s, typical of a small regional ISP aggregating various allocations.

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: 445 networks and 1,817 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.
