that’s a good question. initially, i thought this might have been
allocated to vodacom/one of their clients, but some whois digging shows
for those of you that did not know, you can get a “history” from
objects in the whois database like this:
# whois -h whois.afrinic.net 18.104.22.168/19 --list-versions
and see changes between versions like this:
# whois -h whois.afrinic.net 22.214.171.124/19 --diff-versions 1:2
and see specific snapshots like this:
# whois -h whois.afrinic.net 126.96.36.199/19 --show-version 1
so this was always a canar prefix. and vodacom had no reason to
register those objects imho.
anyway, more homework for the canar team..!
