Abstract
The present invention relates to the field of communications, and in particular, relates to a method for obtaining an Internet Protocol (IP) address of a Dynamic Host Configuration Protocol version 6 (DHCPv6) server, a DHCPv6 server, and a DHCPv6 communication system. The method is applied in a scenario of communication through a DHCPv6 relay agent, and includes: receiving, by a DHCPv6 server, a message of a DHCPv6 client forwarded by a DHCPv6 relay agent; sending, by the DHCPv6 server, a response message to the DHCPv6 client through the DHCPv6 relay agent, in which a payload of the response message carries an IP address of the DHCPv6 server, so that the DHCPv6 client obtains the IP address of the DHCPv6 server from the response message.
