Due to the shortage of IPv4 addresses, many hosts are currently assigned to a single IPv4
address by using one or a number of NAT devices. However, numerous NAT devices cannot …

To transition to IPv6, ISPs must determine how to configure IPv4 over IPv6 networks using
the Dynamic Host Configuration Protocol (DHCP). However, multifarious requirements result …

This document describes the Dynamic Host Configuration Protocol for IPv6 (DHCPv6): an
extensible mechanism for configuring nodes with network configuration parameters, IP …

Sharing IPv4 addresses is important for IPv4 service continuity when the Internet transitions
to IPv6. The IETF proposes IPv4 address sharing during the transition period. This article …

IPv6 has been an inevitable trend with the depletion of the global IPv4 address space.
However, new IPv6 users still need public IPv4 addresses to access global IPv4 …

DHCPv4 over DHCPv6 (RFC 7341) is a mechanism for dynamically configuring IPv4 for use
as an over-the-top service in an IPv6-only network. Softwires are an example of such a …

In IPv6-only provider networks, transporting IPv4 packets encapsulated in IPv6 is a common
solution to the problem of IPv4 service continuity. A number of differing functional …

During the transition from IPv4 to IPv6, customer equipment may have to support one of the
various transition methods that have been defined for carrying IPv4 packets over IPv6. This …
