IPv6 resources

Motivation

• Apple tells app devs to use IPv6 as it's 1.4 times faster than IPv4

Documentation

• IPv6 documentation prefix 2001:db8::/32

Training

1. RIPE NCC introduction to IPv6 Course

Videos

• RIPE NCC::Educa IPv6-only

Miscellaneous

• Bogons (or full bogons) are blocks of address space that should not be used on the public Internet, because they have not yet been allocated to someone or are reserved for special use that does not include routing on the public Internet. One example is the IPv6 documentation prefix 2001:db8::/32.
• RIPE NCC IPv4 Pool
• All the IPv6 Multicast addresses

"Calculations"

• RIPE NCC IPv6 CIDR chart
• IPv4 uses 32 bits for the address space, while IPv6 uses 128 bits. This is 4 times more bits available for addressing devices on the Internet. According to some estimates, you can assign 1564 addresses to each square meter of our planet!
• 64:ff9b::/96 - well known reserved address space for NAT64. Not globally Unique.
• 192.0.0.0/29 CLAT reserved space in 464XLAT RFC6877
• NDP RFC4861

Security

• RA Guard, defined in RFC6105
• SEcure Neighbor Discovery (SEND) RFC3971
• Team Cymru Fullbogons list

ICMPv6

ICMPv6 is crucial for IPv6.

Without ICMPv6, an IPv6 network will not work. All the Neighbour Discovery messages are ICMPv6 messages.

Disabling ICMPv6 completely will cause your IPv6 network to fail.

The following ICMPv6 messages are critical and should never be disabled.

• Error messages
• Packet too big
• Destination unreachable
• Time exceeded
• Parameter problem
• Neighbour Discovery Protocol messages
• Router solicitation
• Router Advertisement
• Neighbour solicitation
• Neighbour Advertisement
• Redirect

• Neighbour Discovery Protocol (NDP)
