AS8374 PLUSNET Plus network operator in Poland
Mobile ARIN Cable/DSL/ISP
Summary
Polkomtel (Plus)
isp mobile legacy
PLUSNET is the routing AS of Polkomtel Sp. z o.o., the Polish operator behind the Plus mobile brand. It is registered to Polkomtel and carries the Plus network's subscriber traffic.
What it's used for
- Mobile internet for Plus subscribers. Reverse DNS is unambiguous: addresses resolve as
apn-IP-ADDR.dynamic.gprs.plus.pl, with a matchingapn-IP-ADDR.static.gprs.plus.plform on the ranges sold with fixed addressing. - Fixed-wireless and LTE home internet, which Plus markets heavily in Poland alongside the phone business.
Notable
- An eyeball network, and specifically a mobile one. The
gprsin the reverse names marks the space as packet-core addressing handed to handsets and routers, not to servers, so it geolocates to subscribers rather than to datacentres. - Roughly 420,000 IPv4 addresses across a modest number of large blocks (
37.248.0.0/16,46.76.0.0/15,37.109.0.0/16and others), which is the shape of a national mobile core rather than a hosting inventory. - Plus is part of the Cyfrowy Polsat group, which pairs the mobile network with a large Polish media and pay-TV business.
Interesting
- The handle is a name trap. This is not the British ISP Plusnet, a BT brand that is a different AS entirely. The Polish "PLUSNET" is simply the network arm of Plus, and for years Polkomtel's network company was actually named PLUS NET Sp. z o.o. before it was folded back into Polkomtel.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
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 1,775 prefixes, as published 2026-10-11. 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.
