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 Vodafone

Vodafone is a mobile network operator in the United Kingdom, run by Vodafone Limited under VodafoneThree Holdings Ltd, formed by the merger of Vodafone and Hutchison 3G UK. AS25135 is the ASN documented as carrying its mobile traffic. Vodafone UK uses MCC 234 with MNC 15.

The registry lists eleven ASNs for Vodafone in the United Kingdom. AS25135 carries the mobile network and at the last probe announced 25 IPv4 prefixes and one IPv6 prefix. AS5378, which PeeringDB names Vodafone UK, announced 23 IPv4 prefixes and one IPv6 and is recorded as fixed broadband. AS25310, in PeeringDB as Vodafone (Access Network UK) with the type Cable/DSL/ISP, announced 4 IPv4 prefixes and is the former Cable and Wireless Worldwide access network. AS1273 announced 194 IPv4 prefixes and 2 IPv6 as the group backbone. The remaining seven announced nothing.

An address whose origin ASN is AS25135 is routed by Vodafone's mobile network in the United Kingdom. Addresses originating from AS5378 or AS25310 are Vodafone fixed broadband, and AS1273 is the group backbone rather than the UK consumer mobile network, so neither should be read as mobile. AS13144 is registered to Vodafone Limited with no documented role, so an address behind it could be mobile, fixed or enterprise, and the ASN alone does not settle it. Vodafone runs 4G LTE and 5G.

Research note. Consumer mobile: AS25135 - PeeringDB name 'Vodafone UK Packet Backbone' (org 14734); RIPEstat holder Vodafone Limited (ORG-VI6-RIPE, Newbury), announcing 26 prefixes incl. 88.82.0.0/19 and 212.183.128.0/20. AS5378 - PeeringDB 'Vodafone UK' (website vodafone.co.uk, org 15059), RIPEstat holder Vodafone Limited (ORG-VL225-RIPE), announces 24 prefixes incl. 90.240.0.0/14, 62.49.0.0/16, 83.104.0.0/14 - these are Vodafone UK fixed broadband ranges, role fixed (role assignment by prefix pattern; PeeringDB info_type blank). AS25310 PeeringDB: 'former Cable&Wireless Worldwide Access Network, now owned by Vodafone', backbone refs 'UK - AS2529, Global - AS1273'. AS2529 (DEMON-INTERNET, descr Vodafone Ltd) announces nothing and was not in the candidate list. AS1273 whois descr 'Vodafone Group PLC' - group backbone, not the UK consumer mobile network. Unannounced legacy objects (13144, 203237, 6749, 5551, 5388, 6847, 8709, 6660, 6757, 8760, 13217, 8576, 5428): all hold 0 prefixes per RIPEstat; VODAFONE ENTERPRISE EQUIPMENT LIMITED objects (ORG-VEEL1-RIPE) are ex-Cable&Wireless Worldwide/Energis enterprise ASNs; listed 11 of 18 candidates. Parent: vodafone.co.uk footer - 'Vodafone Limited, Registered in England and Wales, Company No 01471587' and 'The Nation's Network means the biggest network infrastructure created by VodafoneThree Holdings Ltd through the merger of Vodafone & Hutchison 3G UK'; the Vodafone Group shareholding percentage was not stated on the pages fetched. MCC/MNC: of the 7 candidate rows only 234-15 is confirmed Operational for Vodafone UK (LTE + 5G bands). Dropped: 234-27 = Teleena / Tata Communications Move UK (MVNO, not Vodafone); 234-07 = former Cable & Wireless Worldwide, 'Not operational, MNC withdrawn'; 234-77 = Vodafone UK but status Unknown; 234-89, 234-91, 234-92 not present in the Wikipedia UK table (235-91 Spitfire and 235-92 C&W withdrawn exist under MCC 235, both non-consumer). Generations: vodafone.co.uk/network/5g - 'Experience amazingly fast 5G speeds - around 10 times faster than 4G' and 'With 4G connectivity, you can expect: Average speeds of 23 - 35Mbps'.

Check whether an IP belongs to Vodafone

Look up the origin ASN of the address and compare it with the table above. RIPEstat answers for any address, and the RADB whois mirror lists the routes registered under an ASN.

Questions

What is Vodafone UK's ASN?
The registry records AS25135, held by Vodafone Limited, as the ASN carrying Vodafone's mobile traffic in the United Kingdom. Ten other Vodafone ASNs are recorded, covering fixed broadband and legacy enterprise objects, and most of them announce no prefixes.
What is the MCC/MNC of Vodafone UK?
Vodafone UK uses mobile country code 234 with mobile network code 15. That is the only row the registry confirms as operational for this network; other 234 codes once linked to Vodafone are recorded as withdrawn or of unknown status and are not listed here.
Is an IP from AS1273 a mobile IP?
No. AS1273 is recorded as an enterprise ASN and the registry describes it as the Vodafone group backbone rather than the UK consumer mobile network. An address originating there is routed by Vodafone but should not be classified as a mobile connection.

Where Vodafone meets other networks

PeeringDB records Vodafone as a participant at internet exchanges in 12 cities. Each city page lists the exchanges there and the other networks present.

Network cities in the United Kingdom: London, Manchester, Slough, Edinburgh, Leeds.

ASN and prefix data describe how the operator's networks are registered and announced. They do not identify an individual subscriber or where a device is, since carriers route traffic from many areas through shared gateways.
