Re: [dnssd] Review of draft-ietf-dnssd-hybrid-00

[Tom Pusateri <[e-mail]>]

Thanks for the clarification Harald.

For reference, "on-link" for IPv6 is defined in RFC 4861 Section 2.1 and updated by RFC 5942 Section 3.
For IPv4, Section 3.3.1.1 of RFC 1122 calls this a "connected network”.

I think “on-link” may be the right term to use. But it may have to be defined for IPv4.

In my home network connected via broadband to a big TelCo I have four IPv6 subnet simulatenously: first, the obvious fe80::/10 link-local subnet; next, my own internally stable addresses coming from one of the many fd00::/8 ULA subnets; then a global preferred IPv6 subnet; and finally a deprecated IPv6 subnet that is due to the overlapping rolling subnet addresses we get over here with those "All-IP" broadband access.
