Summary
SIA Tet
isp legacy
TET_LV is SIA Tet, Latvia's incumbent fixed-line telecommunications operator. The company was known as Lattelecom until it rebranded to Tet in 2019.
What it's used for
- Fixed broadband, television and telephony for Latvian homes and businesses, plus the corporate and hosted services Tet sells on top.
- Around 84,000 IPv4 addresses, sized for a national eyeball network serving a country of roughly two million people.
Notable
- This is the country's main incumbent access network, so the address space is dominated by residential subscribers. Traffic is heavily inbound, the classic eyeball profile.
- Tet peers extensively at Latvian and Baltic exchanges and with its Baltic neighbours, keeping regional traffic off long-haul transit.
Interesting
- Tet's routing policy reads like a map of the Latvian market: explicit sessions with Bite, Balticom and other domestic operators sit next to full transit from international carriers. In a small country the incumbent ends up peering with almost everyone.

Internet exchanges
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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
