In IPv4, a host that wants to communicate with another host on the network needs to have an IP address acquired either by means of DHCP or by manual configuration. Internet Protocol version 4 (IPv4) is the fourth version in the development of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet, and was the first version deployed for production in the ARPANET in 1983.Pv4 uses 32- bit (four-byte) addresses, which limits the address space to 4294967296 (2 32) addresses. This limitation stimulated the development of IPv6 in the 1990s, which has been in commercial deployment since 2006. The Anatomy of an IPv4 Address Each device on a network must be uniquely defined. At the Network layer, the packets of the communication need to be identified with the source and destination addresses of the two end systems.or each IPv4 address, some portion of the high-order bits represents the network address. At Layer 3, we define a network as a group of hosts that have identical bit patterns in the network address portion of their addresses. Within the IPv4 address range of a network, the lowest address is reserved for the network address. This address has a 0 for each host bit in the host portion of the address. Broadcast Address. The IPv4 broadcast address is a special address for each network that allows communication to all the hosts in that network.To send data to all hosts in a network, a host can send a single packet that is addressed to the broadcast address of the network.or each IPv4 address, some portion of the high-order bits represents the network address. At Layer 3, we define a network as a group of hosts that have identical bit patterns in the network address portion of their addresses. Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.nternet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. Translation. Address Family Translation (AFT), or simply translation, facilitates communication between IPv6-only and IPv4-only hosts and networks (whether in a transit, an access, or an edge network) by performing IP header and address translation between the two address families.ranslation.

IPv6 over IPv4 tunneling. Tunneling is a mechanism to allow IPv6 domains that are connected via IPv4 networks to communicate with each other, or to allow isolated IPv6 hosts that are not directly connected to an IPv6 router but only to IPv4 machines to reach the wider IPv6 network.Pv6 over IPv4 tunneling. Tunneling is a mechanism to allow IPv6 domains that are connected via IPv4 networks to communicate with each other, or to allow isolated IPv6 hosts that are not directly connected to an IPv6 router but only to IPv4 machines to reach the wider IPv6 network. Each bit of the address is ANDed with the corresponding bit of the subnet mask. Because all the bits of the subnet mask that represent host bits are 0s, the host portion of the resulting network address becomes all 0s. Recall that an IPv4 address with all 0s in the host portion represents the network address.or each IPv4 address, some portion of the high-order bits represents the network address. At Layer 3, we define a network as a group of hosts that have identical bit patterns in the network address portion of their addresses.

NAT—PT is an IPv6-to-IPv4 translation mechanism, as defined in RFC 2765 and RFC 2766, that allows IPv6-only devices to communicate with IPv4-only devices and vice versa. This modules describes Network Address Translation (NAT)—Protocol Translation (PT) and explains how to configure the feature.tatic NAT-PT uses static translation rules to map an IPv6 address to an IPv4 address. IPv6 network nodes communicate with IPv4 network nodes using an IPv6 mapping of the IPv4 address that is configured on the NAT-PT device.
