Summary
JT (Jersey) Limited
isp residential legacy
JT (JT) — formerly Jersey Telecom, the States-of-Jersey-owned incumbent operator for Jersey and Guernsey, and the ISP behind the jtglobal.com and jtibs.net address space.
What it's used for
- Retail fixed broadband and mobile in the Channel Islands. The rDNS is explicitly eyeball: dynamic pools under
IP-ADDR.dyn.jtglobal.comand residential customer names of the formuserNNN.resNN.jtibs.net, alongside generic reverse-octetIP-ADDR.jtglobal.comnames for the static assignments. - Business and public-sector connectivity on the islands sits in the same inventory, along with infrastructure from operators JT absorbed —
newtelsolutions.net(Newtel) andguernsey.netnames still resolve inside the announced space.
Notable
- About 71,000 IPv4 addresses across roughly 58 prefixes, with a peering count (dozens of neighbours) that is high for an island of ~100,000 people. JT sells wholesale and international services well beyond its home market.
- Part of the inventory is ARIN and APNIC space rather than RIPE, reflecting JT's global IoT/roaming-SIM business rather than any brokered address holding: every block resolves into JT's own domains.
- Jersey was one of the first places in the world with island-wide fibre-to-the- premises, JT having completed the rollout to essentially every home.
Interesting
- Sister-island incumbent AS8680 (Sure) sits one number away and covers the same archipelago from Guernsey — adjacent AS numbers for competing island carriers.

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: 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.
