TRA has encouraged the transition to IPv6 in many ways such as:

1. Monitoring the operators progress in their transitional plan to IPv6.

2. By attending meeting regarding IPv6 which helps in increasing the knowledge of IPv6 in Oman .

3. The Type Approval Department at TRA encouraged the private sectors ( Dealers of telecom equipment) to consider the transition to IPv6 by type approving equipments that is compatible with IPv6.

About IPv6

Internet Protocol version 6 (IPv6) is the next-generation Internet Protocol version designated as the successor to IPv4. It was defined in December 1998 by the Internet Engineering Task Force (IETF) with the publication of an Internet standard specification, RFC 2460. IPv6 provides for an expanded address space. It uses 128-bit addressing (versus 32 bits in IPv4), which results in 340 undecillion unique addresses that is, 340 billion billion billion billion.

IPv6 addresses typically have two parts: a 64-bit network prefix and a 64-bit host address. The host address can be assigned sequentially or automatically generated from the interfaces MAC address. The IPv6 addressing structure uses hexadecimal notation, normally written as eight groups of four hexadecimal digits, and colons replace the periods used in IPv4, as in the following example:

2001:0db8:85a3:0000:1319:8a2e:0370:7344

IPv6 has four address types: unicast (one-to-one), anycast (one-to-nearest), multicast (one-to-many), and a reserved class. A single interface may be assigned multiple IPv6 addresses of unicast, anycast, or multicast addresses. Note that IPv6 does not support broadcasting.
IPv6 is designed to be an evolutionary step from IPv4. It can be installed as a normal software upgrade in Internet devices and is interoperable with IPv4. IPv6 runs well in high-performance networks, such as Gigabit Ethernet and ATM networks, and it is also efficient for low-bandwidth networks such as wireless networks. In addition, it provides a platform for new Internet functionality that will be required in the near future. IPv6 simplifies the packet header format (see figure below that shows IP Packet Header). It supports autoconfiguration and multihoming. IPv6 includes the DiffServ Code Point (DSCP) in the traffic class, and it addresses authentication and privacy capabilities.



Benefits of IPv6 include improved routing efficiency due to the streamlined header format as well as simplified administration. QoS capabilities are also enhanced because the specification includes a flow label to support real-time traffic. Finally, IPv6 offers better security mechanisms, mandating the use of IPsec and IKE . The encryption extension known as the Encapsulating Security Payload (ESP) service renders the packets payload data illegible unless the recipient has the proper key to unscramble the data. Administrators can choose to encrypt only the transport and data payload of a packet or the entire packet, including headers and extensions.

The architecture for IPv6 is defined in RFC 3513, "IP Version 6 Addressing Architecture," which is available at www.ietf.org/rfc/rfc3513.txt and provides complete information on IPv6 addressing, rules, and exceptions. IPv6 addressing rules are covered by multiple RFCs.
