1 IPv6

IPv6 (Internet Protocol version 6) is the successor to the most common Internet Protocol today (IPv4).

This is largely driven by the fact that IPv4 32-bit addresses are quickly being consumed by the ever-expanding sites and products on the Internet. IPv6 128-bit address space should not have this problem for the foreseeable future.

IPv6 addresses, in addition to being longer, are distinguished from IPv4 addresses by the use of colons ":", e.g. 2001:470:8929:4000:201:80ff:fe3c:642f. An IPv4 address is noted by 4 sets of decimal numbers separated by periods ".", e.g. 192.168.10.1.

Please note that IPv6 addresses should be written between [ ] to allow port numbers to be set.

For instance, [fd0f:8b72:5::1]:5060.


1.1 IPv6 Availability

DGW supports IPv6 except for:
  • CPE WAN Management Protocol (CWMP)/TR-069
  • DHCP embedded sever
  • IP Routing
  • Local Firewall (LFW)
  • Network Firewall (NFW)
  • Network Address Translation (NAT)
  • Online Certificate Status Protocol (OSCP)
  • Remote Authentication Dial In User Services (RADIUS)
  • Session Border Controller (SBC)
  • Simple Network Management Protocol (SNMP)
  • PPPoE

IPv6 link-local addresses start with fe80 and must include the scope identifier

Therefore, the format of a link-local address is: [IPv6 link-local%ScopeIdentifier].

The scope identifier corresponds to:

  • On Windows: the network link used to contact the IPv6 link-local address.
  • On Linux: the link name or the interface number.

For example, if the unit must contact a server at the IPv6 link-local fe80::201:80ff:fe3c:642f address, you must check on which network link the server is available. Some units have WAN or LAN. If it is on the WAN link, the IP address would then be "[fe80::201:80ff:fe3c:642f%wan]".


2.1 Locating the Scope Identifier of fe80 IPv6 Addresses on Windows

Context

Important

If the Mediatrix unit is configured to use IPv6 addresses and the firmware is downgraded to a version that does not support IPv6, then all IPv6 networks are deleted.

Steps

  1. Open the Windows Command Line interface.
  2. Type ipconfig.
  3. Locate the IPv6 address.

    Note

    The IPv6 address starts with fe80.

  4. Locate the interface number in the IPv6 address.

    Note

    the interface number is at the end of the address, after the %.

Result

In the following example, the interface number of the [fe80::201:80ff:fe3c:642f%4] IPv6 address is 4.

2.2 Locating the Scope Identifier of fe80 IPv6 Addresses on Linux

Context

Important

If the Mediatrix unit is configured to use IPv6 addresses and the firmware is downgraded to a version that does not support IPv6, then all IPv6 networks are deleted.

Steps

  1. Open the Linux Command Line interface.
  2. Type ipconfig.
  3. Locate the IPv6 address.

    Note

    The IPv6 address starts with fe80.

  4. Locate the interface number in the IPv6 address.

Result

In the following example, to contact the IPv6 link-local IPv6 address "fe80::201:80ff:fe3c:642f", you would use: [fe80::201:80ff:fe3c:642f%2] or [fe80::201:80ff:fe3c:642f%eth0].
