In the appendix we use v and h represent the IPv4 subnet (hex) and host
index (hex). The length of v is (s), and the length of h is (k) as shwon
in Figure 2.
Could you kindly elaborate that more? How could a specific
IPv4-translatable address be derived? I can't fully follow the
algorithm. It would be great if you could take example, like how
2001:db8:a4a6:4614:c0:a801:140:100 (item#2) could be generated.
The description of 2001:db8:a4a6:4614:c0:a801:140:100 (item#2)
2 192.168.1.1 1 1 2001:db8:a4a6:4614:c0:a801:140:100
2001:db8:a4a6:46 14: c0:a801:1 40:1 00
^ ^ ^ ^ ^
domain-prefix cpe-index u-octet embed IPv4 suffix
zero-pading
(56 bits) (8 bits) (8 bists) (32 bits) (16 bits) (8 bits)
(2+4+2) (4+12 bits)
note that
cpe-index= 14,
where 2 bits identify the IPv4 subnet and 4 bits identify the host
index. there are 2 bits left with zero-padding.
suffix= 40:01,
where 4 bits identify the ratio, 12 bits identify the host index.

Thanks
