Autonomous systems
Holder names and prefix counts come from the RIPE NCC's RIPEstat Data API, fetched on 2026-09-06. Role and confidence come from the evidence linked in each row; "confirmed" means a PeeringDB or RIPEstat record, or the operator's own site, names the operator.

Mobile network codes
The MCC identifies the country and the MNC identifies the operator inside it. Together they appear in the IMSI of every SIM on the network and in device diagnostics; they are how a handset knows which network it is on.
About T-Mobile Polska
All four ASNs in the registry are registered to T-Mobile Polska S.A. under the name TMPL, and all four announce address space. AS12912 holds the mobile role and announces 48 IPv4 prefixes against 2 IPv6 prefixes at the last probe; PeeringDB records it as "T-Mobile Polska" with an info type of Cable/DSL/ISP. AS6714, AS8246 and AS8938 each announce a single IPv6 prefix and no IPv4 at all, and no PeeringDB record was retrieved for any of them. The registry documents no role for those three.
An address whose origin ASN is one of these four is routed by T-Mobile Polska. AS12912 is the one the registry documents as mobile, and it holds nearly all of the operator's announced IPv4 space. For AS6714, AS8246 and AS8938 the role is not documented, so an address from those IPv6 prefixes could be mobile, fixed or enterprise, and the ASN by itself does not settle which. The second code pair, 260-34, belongs to the shared LTE network run with Orange Polska.
Research note. Parent: firma.t-mobile.pl states T-Mobile Polska is 'częścią globalnej Grupy Deutsche Telekom'. AS12912 (PeeringDB name 'T-Mobile Polska', aka TMPL/TM-PL, website t-mobile.pl, type Cable/DSL/ISP; 50 announced prefixes incl. 46.204.0.0/15, 37.31.0.0/17, 188.146.128.0/17; bgp.he.net prefix descriptions reference 'blueconnect', T-Mobile Polska's mobile-broadband brand) is the main ASN carrying the consumer mobile network. AS6714, AS8246, AS8938 are all named TMPL / T-Mobile Polska S.A. in RIPEstat and RIPE DB (address ul. Marynarska 12, Warsaw) but each announces only a single IPv6 /48 (2001:4190:8032::/48, 2001:4190:8025::/48, 2001:4190:8024::/48); purpose not stated - role unknown. PeeringDB for 6714/8246/8938 not retrieved (throttled). MCC/MNC: candidates 260-11 (Polkomtel/Plus, former Nordisk) and 260-90 (Polska Spolka Gazownictwa) belong to other companies - rejected. Added from Wikipedia: 260-02 T-Mobile Polska S.A. operational (former Era; GSM 900/1800, LTE 900/1800/2100, 5G 2100/3500; UMTS shut down Apr 2023) and 260-34 'NetWorkS!' registered to T-Mobile Polska S.A. - the shared T-Mobile/Orange LTE 800/2600 network. Wikipedia also lists 260-10/26/30/31/42 as T-Mobile Polska with status Unknown (ex-MVNO/legacy codes) - not included. Generations: t-mobile.pl/5g states 5G network >1 Gb/s and coverage checker lists LTE 4G.

What is T-Mobile Polska's ASN?
The registry records four confirmed ASNs for T-Mobile Polska, all registered as TMPL: AS12912, AS6714, AS8246 and AS8938. AS12912 is the one documented as carrying the mobile network and announces almost all of the operator's IPv4 space. The other three announce one IPv6 prefix each and have no documented role.
What is the MCC/MNC of T-Mobile Polska?
Two code pairs are recorded, both under MCC 260. MNC 02 is the operator's own network, written 260-02. MNC 34 is registered to T-Mobile Polska S.A. as NetWorkS!, the LTE network shared with Orange Polska, written 260-34.
Is an IP from AS12912 a mobile IP?
AS12912 is the T-Mobile Polska ASN the registry documents as carrying mobile traffic, so an address originating there is routed by that network. PeeringDB types the ASN as Cable/DSL/ISP, and the registry does not separate mobile from fixed address space within it.
