I would probably create a custom fact for this
IP_ADDR="192.168.10.21"
y=#{IP_ADDR}.split('.')[3].to_i).divmod(2)[1]
puts y
something like...
$resolv.conf_pool = "resolv.conf-pool-A"
#{IP_ADDR}.split('.')[3].to_i).divmod(2)[1] == 0 ? "resolv.conf-pool-A" :
"resolv.conf-pool-B"
and then 'source' the actual resolv.conf file per pool-A or pool-B result
Should be relatively easy to create.
