Vodafone Czech Republic ASN, MCC/MNC and IP prefixes

Vodafone Czech Republic is a mobile network operator in the Czech Republic and part of Vodafone Group. The registry records AS16019 as the ASN carrying its mobile network, with AS15512 and AS29113 also held by the operator but no role documented for either. Its mobile country and network code is 230-03. It runs 4G LTE and 5G.

The registry lists three ASNs held by Vodafone Czech Republic. AS16019 is the mobile-carrying one and the only one of the three announcing routes. At the last probe it announced 90 IPv4 prefixes against 17 IPv6 prefixes, the widest IPv6 spread the registry records for the operator. PeeringDB lists it under the name Vodafone Czech Republic and gives it no information type. AS15512 and AS29113 announced no prefixes and have no PeeringDB entry, and the registry documents no role for either.

An address whose origin ASN is AS16019 is routed by Vodafone Czech Republic, and since the registry marks that ASN as the mobile one and no other Vodafone ASN announces routes, the operator's Czech traffic reaches the public internet through it. That includes handsets and fixed connections, so the ASN identifies the operator rather than the access type. AS15512 and AS29113 announce nothing, so no live address maps back to them, and if either starts announcing, the registry has no documented role to say whether the space would be mobile, fixed or enterprise.

Research note. AS16019 (VODAFONE-CZ-AS): PeeringDB name 'Vodafone Czech Republic', website vodafone.cz; RIPEstat announced; only announced Vodafone CZ AS, so carries the consumer mobile network. AS15512 (VODAFONE-CZ-AS-3) and AS29113 (VODAFONE-CZ-AS-5) are held by Vodafone Czech Republic per RIPEstat but are not announced and have no PeeringDB record; role unknown. MNC 230-99 dropped: listed as not operational (CTU R&D centre, licence expired Jul 2012). The duplicate 230-03 candidate row was collapsed to one. Parent: vodafone.cz states 'Vodafone Czech Republic je součástí mezinárodní skupiny Vodafone'. 5G: vodafone.cz/5g-sit states nearly 97% of people in 5G reach and unlimited 5G tariffs; about page mentions 3G shutdown in favour of 4G/5G.
