Summary
Primetel PLC (NSP-INTL)
isp legacy
NSP-INTL is held by Primetel PLC, a Cypriot telecoms operator selling fixed broadband, telephony, mobile and TV. The registry description states the AS's job plainly: it is the transit AS for PrimeTel (AS16229), SpiderNet (AS5425) and NetWay (AS30916) traffic — the group's international-transit front door, sitting between those networks and upstreams such as Cogent, Telia, Level 3 and GTT.
What it's used for
Two things at once, and the addresses settle which one dominates. Although the AS exists to carry group transit, the space it originates is overwhelmingly Cypriot subscriber space: cpe-155157.ip.primehome.com, cpe-987528.ip.primehome.com, cpe-864512.ip.primehome.com and so on across every large block sampled. Those are customer-premises equipment records keyed by subscriber ID under PrimeTel's primehome.com broadband zone.
Mixed in are the operator's own routers (j1.lim.prime-tel.net, likely Limassol) and at least one business customer's gear (mikrotik-hq-server.thunderworx.net).
Notable
- A handle that says transit over an inventory that says eyeball. The transit role is real, but it is exercised on behalf of sibling ASNs whose traffic transits here — the addresses under this origin are homes.
- Subscriber-ID-in-hostname rDNS (
cpe-NNNNNN) is a common European broadband pattern and makes the space trivially identifiable as residential access.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
