tl;dr:  the address families are separate and unrelated.  don’t build 
dependencies between them.

in addition to what barry’s already written:
m at levonent:~# whois -h whois.afrinic.net 196.60.255.0 | grep -A3 inetnum
inetnum:        196.60.0.0 - 196.60.255.255
netname:        IXP-RESERVATIONS
descr:          This block is reserved for IXPs as per policy 
AFPUB-2014-GEN-004
descr:          For IXP peering purposes

ie, when you apply for your next block of IPv4 addresses for your 
peering lan, at afrinic, you won’t be getting addresses assigned from 
196.223.x, but from 196.60.y.   so the “consistency” that you are 
aiming for, would be unrealised in the future.  unless, of course, you 
plan to change your IPv6 addresses at the same time - and that’s a 
totally unnecessary pain.
