What is 3gppnetwork.org [RESOLVED]

The domain name 3gppnetwork.org is owned and operated by 3GPP (3rd Generation Partnership Project) network architecture, this is specifically related to mobile networks. 

3gppnetwork.org is the root domain for most Mobile Phone/Cell-over-WiFi calling. Phones participating in WiFi calls make ESP protocol connections to hostnames like epdg.epc.mnc030.mcc234.pub.3gppnetwork.org

The subdomains represent the country and the provider. For example epdg.epc.mnc030.mcc234.pub.3gppnetwork.org is EE in the United Kingdom.

Mobile Country Codes (MCC) are used in wireless telephone networks (GSM, CDMA, UMTS, etc.) in order to identify the country which a mobile subscriber belongs to. In order to uniquely identify a mobile subscribers network the MCC is combined with a Mobile Network Code (MNC). The combination of MCC and MNC is called HNI (Home network identity) and is the combination of both in one string (e.g. MCC= 262 and MNC = 01 results in an HNI of 26201). If you combine the HNI with the MSIN (Mobile Subscriber Identification Number) the result is the so called IMSI (integrated mobile subscriber identify). You can use this website to lookup any codes worldwide.

Wi-Fi calling allows mobile phone users to make and receive calls over a Wi-Fi network rather than relying on the carrier’s cellular network. This service enables users to place calls and send text messages even when they are outside cellular coverage, as long as they are connected to Wi-Fi. Wi-Fi calling is supported by most major mobile providers worldwide.

Some uses for this domain include :

• Network Configuration: Mobile devices and Wi-Fi routers may use this domain to configure network settings, access point names (APNs), or for other network services.
• Service Discovery: It can be used for service discovery in mobile networks, enabling devices to find specific services offered by a network operator.
• Interoperability: This domain helps ensure that devices from different manufacturers can work seamlessly on the same network, following the standards set by 3GPP.
• Access to Network Resources: It may also be used to access specific resources or services provided by the network operator for users connected to that network.
