Cellular networks are the backbone of mobile communication and are used by millions of people worldwide. The latest version of the Internet Protocol (IP), IPv6, can be used over cellular networks to provide a large address space and advanced features for routing and addressing.
In this blog post, we will discuss the basics of IPv6 over cellular networks, including the frame format and addressing used in this combination of technologies.
IPv6 over cellular networks refers to the use of IPv6 on mobile networks, such as 3G, 4G, and 5G. IPv6 can be used in the same way as IPv4 over cellular networks, but there are some differences in the frame format and addressing used in IPv6 over cellular networks.
A cellular frame is the basic unit of data transmission in a cellular network. It consists of a header and a payload, as well as some other fields that are used for error detection and correction.
The header of a cellular frame includes several fields that are used to identify the source and destination of the frame. These fields include:
IPv6 addresses are fundamental component of IPv6 over cellular networks, as they are used to identify devices and route packets across the network.
IPv6 addresses used in cellular networks can be of two types: global addresses and link-local addresses.
Global addresses are used for communication across different cellular networks or over the Internet. They are assigned by Internet Service Providers (ISPs) or other organizations and are globally unique.
Global addresses are identified by a prefix that identifies the network and a 64-bit interface identifier that is typically derived from the device's MAC address or another unique identifier.
Link-local addresses are used for communication within a single cellular network, similar to link-local addresses used in Ethernet or Wi-Fi. They are automatically assigned to an interface when it is initialized and are only valid within the local network segment.
Link-local addresses are identified by the prefix fe80::/10 and the interface identifier that is derived from the device's MAC address or another unique identifier.
IPv6 over cellular networks is becoming increasingly important as more people use mobile devices to access the Internet. IPv6 provides a large address space and advanced features for routing and addressing, while cellular networks provide a flexible and convenient way to connect to the Internet.
In this blog post, we discussed the basics of IPv6 over cellular networks, including the frame format and addressing used in this combination of technologies. We explained how cellular frames are structured and how IPv6 addresses are assigned and used for communication within and between cellular networks.
By understanding the basics of IPv6 over cellular networks, network administrators can ensure that their networks are configured correctly and are capable of efficiently forwarding data across different cellular networks and the Internet.
