Hey misc@,

I'm trying to install a null route for an IPv6 block, but I get:

$ sudo route add -inet6 2607:f2f8::/32 ::1 -blackhole
route: 2607:f2f8::/32: bad value

What is bad about that v6 address?

Note that even when omitting -blackhole, it will still error.

I'm running OpenBSD 4.4 on amd64 arch.  Stock GENERIC kernel.

I'm sure it's simple but I don't deal w/ OpenBSD routers much.

Thanks.

I believe you want:

$ sudo route add -inet6 -net -blackhole 2607:f2f8:: -prefixlen 32 ::1
