They probably would have been happy with a /96 network except for stateless autoconfig, which is quite nice for some stuff actually.Ok, calling it "classful routing" might be a little melodramatic. I would love to be able to set interfaces on my cisco hardware to /96's,
but
it's not allowed. Autoconfig screws that up. Even if it's not used,

forced to live with it. Linux, BSD, etc. don't care. (and the instant they
do,
I can remove that stupid code.)
Actually, they will - you can set them to any arbitrary value between 1 and 128 (inclusive), atleast on every piece of gear I've tried to use.
I've not tried every vendor out there, but I've noticed some implementations handle /127 just fine from a routing perspective.So far, Cisco's gear is the only IPv6 routers I've messed with. And they will not let you set an interface to anything smaller than a /64. Loopbacks have slightly different rules, but in my case (IPv6 tunnels) that fact hasn't proven very useful.
See above. Maybe true on some gear, or some old IOS, or when using the auto-config key word ... ? /TJ
