Thanks Mark, I'm not much into the cellular realm other than Ethernet
cell-backhaul, which isn't cell at all but rather just hauling Ethernet/vlan
frames across my network as fast as I can :)
...so does what you said mean ipv6 prefixes are delegated to phones ?

Hi Aaron,
Not a sin but you're making more work for yourself if you subnet on
other-than four-bit nibble boundaries. Each character

I thought the only allowed subnet prefix lengths for IPv6 were /64 and
/127. RFC 4291 states:

Well, /112 is not a stupid option (and is far smarter than /64): it contains
the whole last nibble of an IPv6, that is x:x:x:x:x:x:x:1234.
You always put 1 or 2 at the end, and if needed you are still able to address
additional stuff would the point-to-point link become a LAN.
And you don't throw

A /112 means you can always use ::1 and ::2 for you endpoints. Of
course, you could allocate at /112 boundary and still use a /126 (or
even a /127 and use ::0 and ::1).

What subnet mask you are people using for point to point IPs between two
ASes? Specially with IPv6, We have a transit provider who wants us to use
/64 which does not make sense for this purpose. isn’t it recommended to use
/127 as per RFC 6164 like /30 and /31 are common for IPv4.
You can just ig
Hello,
The common recommendations for IPv6 point to point interface numbering are:
/64
/124
/126
/127
/64:
Advantages: conforms to IPv6 standard for a LAN link
Disadvantages: DOS threats against this design. Looping on a true ptp
circuit. Neighbor discovery issues.
/124:
Advantages: supports mu
You should be using /126 or /127 for point to point links that touch
external networks unless you like extraneous NS messages and full neighbor
cache tables. :)
