Re: 16-bit ASN kludge

The proposal was that transit ASNs would begin with 12 leading 0 bits and
non-transit ASNs would not.  As such, 1312 would not be a non-transit ASN.

The proposal wasn't for "parallel" ASN space.  The proposal was to have
a range of ASNs for leaf-networks and a range for transit networks, allowing
transit networks to make more rational (possibly automated) decisions about
route aggregation.

I don't see non-transit ASN leakage as any greater issue than current

If somebody leaks a private ASN, we can tell that it's a private ASN by

If somebody is using '1312' inside their parallel ASN space and
accidentally leaks it, it's a bit harder to diagnose.

And if somebody is leaking 1312, I'll be quite put out... ;)

If it wasn't crypto-signed, it probably didn't come from me.
