How to enable DHCP IPv6 on the D-link and Huawei router

Enabling IPv6 on your fibre router is necessary because the world is running out of IPv4 addresses due to the growing number of internet-connected devices and increased traffic. The main function of IPv6 is to allow for more unique IP address identifiers to be created and assigned.

IPv4 addresses are made up of four sets of one to three-digit numbers, IPv6 uses eight groups of four hexadecimal digits, separated by colons.

  • An example of IPv4 -
  • An example of IPv6 - 2001:0db8:85a3:0000:0000:8a2e:0370:73b4.
What is an IP address? 

An IP or Internet Protocol address is a numerical identifier assigned to each device that connects to the internet. IP addresses allow devices to talk to each other and exchange information.

PPPoE is used for an Openserve and Vodacom connection only.
DHCP is used for all the other fibre providers.
