Abstract Abstract
DS-Lite, defined in RFC 6333, directs IANA to reserve 192.0.0.0/29 DS-Lite, defined in RFC 6333, directs IANA to reserve 192.0.0.0/29
for the B4 element. This memo directs IANA to generalize that for the B4 element. This memo directs IANA to generalize that
reservation to include other cases where a non-routed IPv4 interface reservation to include other cases where a non-routed IPv4 interface
must be numbered as part of an IPv6 transition solution. must be numbered as part of an IPv6 transition solution.

DS-Lite [RFC6333] directs IANA to reserve 192.0.0.0/29 for the Basic DS-Lite [RFC6333] directs IANA to reserve 192.0.0.0/29 for the Basic
Bridging BroadBand (B4) element. This memo generalizes that IANA Bridging BroadBand (B4) element. This memo generalizes that IANA
reservation to include other cases where a non-routed IPv4 interface reservation to include other cases where a non-routed IPv4 interface
must be numbered in an IPv6 transition solution. IANA shall list the must be numbered in an IPv6 transition solution. IANA shall list the
