Unclassified RIPE
Summary
LAN-Optic
isp russia residential business
The AS handle LAN-OPTIC is held by LAN-Optic, Ltd.
What it's used for
- The address space carries subscriber and corporate traffic, evidenced by reverse DNS entries such as
host161-61-254.lanoptic.ruand91.203.210.254.lanoptic.ru, alongside netnames likeLANOPTIC-NETandLAN-optic. - The network announces 16,640 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, with only 4 observed routing neighbours; this high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
- As a Russian internet service provider, the traffic consists primarily of residential broadband subscribers and small business customers connecting to the internet.
Notable
- Registrants for the largest prefixes include LAN-Optic, Ltd, NetArt Group s.r.o., and Petersburg Internet Network ltd., indicating a mix of owned and potentially leased or historically acquired address space.
- The inventory includes a large /19 block registered to NetArt Group and /21 and /22 blocks registered to Petersburg Internet Network, suggesting the AS aggregates space from multiple sources or reflects past acquisitions.
- The address inventory is subdivided into six distinct IPv4 prefixes, ranging from a /19 down to a /24, with the largest block accounting for the majority of the announced address space.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
