I forgot to mention RFC4380 which also embeds a *lot* of additional IP information
within the IPv6 address. There may be others I am also forgetting.

> 
> Hi, the OMNI spec defines an IPv6 link-local address format that embeds another
> IP address/prefix inside the least significant bits:
> 
> https://datatracker.ietf.org/doc/draft-templin-6man-omni-interface/
> 
> The idea behind embedding IP information inside an IPv6 address was first published
>  in RFC1884 (December 1995) where the "IPv4-compatible" and "IPv4-mapped" IPv6
> addresses were defined. (This was the first edition of the IPv6 addressing architecture,
> with the latest edition now as RFC4291.) Later, RFC4214 and RFC5214 put a more formal
> structuring around embedded IP addresses and RFC5969 even went further to move
> the embedded information up into the upper 64 bits of the IPv6 address.
> 
> The genesis of the OMNI concept of embedding additional IP information in the IPv6
> address was introduced in the "AERO(bis)" draft following the publication of RFC6706.
> This format was later cited in RFC7421. Now in the present OMNI draft, we have an
> IPv6 link-local address format where embedded IP information begins immediately
> after the fe80::/10 prefix thereby utilizing up to 112 available bits for encoding useful
> information.
> 
> It has come to my attention that some are skeptical about embedded IP information
> inside an IPv6 address. But, the OMNI draft shows clear benefits for making use of
> these otherwise-wasted bits and follows on from decades-old examples that are
> still in use today. Would love to hear everyone's thoughts on this.
