Summary

Arcus Novus

Lithuania · AI-generated

mobile isp lithuania

ARCUS is operated by Arcus Novus UAB.

What it's used for

  • The address space carries mobile and internet services, as indicated by the registrant netnames Arcusnovus_32-41_LT, Arcusnovus_43-46_LT, and Arcusnovus_48-55_LT associated with ArcusNovus LT NOC.
  • The AS announces 7424 IPv4 addresses across 12 prefixes and 4 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio characteristic of an access or mobile network rather than a transit provider.
  • Traffic from this AS consists of mobile subscriber data and internet services provided by Arcus Novus, a Lithuanian mobile network operator.

Notable

  • Registrants are consistent with the announcer, listing Arcus Novus UAB and ArcusNovus LT NOC for the majority of the inventory.
  • The address inventory is concentrated in the 77.94.32.0/19 range, with prefixes subdivided into /21, /22, /23, and /24 blocks.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
