Claro ASN, MCC/MNC and IP prefixes

Claro is a mobile network operator in Argentina, part of América Móvil. It routes traffic through 2 autonomous systems (AS11664, AS19037), which announced 2,894 prefixes at our last probe, and its SIMs carry MCC/MNC 722-310, 722-320, 722-330.

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 Claro

Claro is a mobile network operator in Argentina, part of the América Móvil group and registered as the legal entity AMX Argentina S.A. The registry records AS11664 as the ASN carrying its mobile network and AS19037 with no documented role. Its MCC/MNC codes are 722/310, 722/320 and 722/330, and the network runs 4G and 5G.

The registry records two ASNs for Claro. AS11664 carries the mobile network; its RIPE holder name is Techtel LMDS Comunicaciones Interactivas S.A., an AMX company, and PeeringDB lists the network as CLARO ARGENTINA with a Cable/DSL/ISP info type. At the last probe AS11664 announced 1,505 IPv4 prefixes and 1,389 IPv6 prefixes. AS19037 is registered to AMX Argentina S.A. and appears in PeeringDB as AMX Argentina, also typed Cable/DSL/ISP, but it announced no prefixes at the last probe and its role is not documented.

An address whose origin ASN is AS11664 is routed by Claro, and the registry documents that ASN as the one carrying the operator's mobile network. The same ASN is Claro's general eyeball network and PeeringDB types it Cable/DSL/ISP, so a single address from it can also be fixed access. AS19037 has no documented role, which means an address originating there could be mobile, fixed or enterprise and the ASN alone does not settle it. The recorded role attaches to the ASN, not to any individual address.

Research note. Legal entity AMX Argentina S.A.; claro.com.ar footer carries the America Movil logo/link and mcc-mnc.org names América Móvil as parent. AS11664: RIPEstat holder is 'Techtel LMDS Comunicaciones Interactivas S.A.' (an AMX company); bgp.tools lists website claro.com.ar, eyeball/home-ISP, 1,505 IPv4 + 1,386 IPv6 prefixes, #2 eyeballs in Argentina; PeeringDB record is titled 'AS11664 - CLARO ARGENTINA' (page seen only via search-result title; API was rate-limited on every attempt). AS19037 AMX Argentina S.A. is confirmed by PeeringDB (aka 'Claro Argentina') but announces no prefixes (RIPEstat announced=false; ipinfo 'Inactive'). MNC 310: mcc-mnc-lookup.com lists it as 'CLARO ARGENTINA / CTI PCS S.A.'; mcc-mnc.org lists operator AMX Argentina S.A. but mislabels the brand as 'Personal'. Candidate row 722/031 returns 'Network Not Found' on mcc-mnc.org; dropped. claro.com.ar/personas/5g states '5G disponible sin costos extra' and contrasts 5G with 4G/3G; mcc-mnc.org 722_320 lists LTE1700. 5G spectrum (Lote 1, 3.300-3.400 MHz) awarded to AMX Argentina S.A. by ENACOM Res. 1473/2023.

Questions

What is Claro Argentina's ASN?
The registry records two. AS11664 is documented as carrying Claro's mobile network and is held by Techtel LMDS Comunicaciones Interactivas S.A., an AMX company. AS19037 is held by AMX Argentina S.A., appears in PeeringDB as Claro Argentina, and announced no prefixes at the last probe.
What is the MCC/MNC of Claro Argentina?
The registry records three rows, all under mobile country code 722: 722/310, 722/320 and 722/330. They are listed for the AMX Argentina S.A. network that trades as Claro. A candidate row 722/031 could not be confirmed against the sources used and is not recorded.
Is an IP from AS11664 a mobile IP?
Not on the ASN alone. The registry documents AS11664 as carrying Claro's mobile network, but PeeringDB records it as a Cable/DSL/ISP network and it is the operator's general eyeball ASN, so an address from it can also be fixed broadband. The registry does not classify individual addresses.

Where Claro meets other networks

PeeringDB records no public exchange presence for Claro, which says nothing about how it reaches other networks privately. These are the Argentina cities where the registry does record exchange and facility capacity.

Network cities in Argentina: Buenos Aires, Mendoza, Rosario.

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.
