Residential RIPE
Summary
Tusass A/S (Tele Greenland)
isp residential legacy
Tele Greenland in the registry handle is now Tusass A/S, Greenland's state-owned national telecommunications operator. It runs essentially all of the island's connectivity: fixed broadband, mobile, the submarine cables to Iceland and Canada, and the satellite links that serve the settlements the fibre does not reach.
What it's used for
Consumer and business Internet access across Greenland. Every sampled address in the announced space resolves into the adsl.gl zone with the classic subscriber-pool pattern host-IP-ADDR.adsl.gl — a generic per-address PTR template applied across 178.170.0.0, 88.83.0.0, 37.230.0.0 and 128.0.70.0 blocks alike. That is an eyeball access network, not backbone or hosting infrastructure.
Notable
- ~34k IPv4 addresses across 26 prefixes plus IPv6 — small in absolute terms, but this is the network for a population of about 56,000 spread over the world's largest island.
- Only one observed BGP neighbour. Greenland's traffic is effectively single-homed onto a Danish upstream; there is no domestic peering fabric to speak of.
- The
.glrDNS zone is one of the few places where a country-code TLD and an ISP's subscriber pool are the same thing.
Interesting
The company rebranded from TELE-POST / Tele Greenland to Tusass in 2020 (the word means roughly "message" or "news" in Greenlandic), but the RIR handle still carries the old name — a routine case of a registry handle outliving the brand.

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
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: 431 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.
