Wait. I think I may have found the problem. Do I need to modify the
script to include each of our subnets in use? e.g we use 10.0.0.0/16,
192.168.x, .y, .z,etc. due to existing subnets from other locations
we've acquired, whereas your example on the wiki is only using
192.168.0.0/24. Snippet from the script that I would need to modify
for our use case:
    case "$numwords" in
       1) # single ip rev zone '192'
          ZoneIP=$(echo "${IP}" | awk -F '.' '{print $1}')
          RZIP=$(echo "${rzoneip}" | awk -F '.' '{print $3}')
          IP2add=$(echo "${IP}" | awk -F '.' '{print $4"."$3"."$2}')
          ;;
       2) # double ip rev zone '168.192'
          ZoneIP=$(echo "${IP}" | awk -F '.' '{print $1"."$2}')
          RZIP=$(echo "${rzoneip}" | awk -F '.' '{print $2"."$1}')
          IP2add=$(echo "${IP}" | awk -F '.' '{print $4"."$3}')
          ;;
       3) # triple ip rev zone '0.168.192'
          ZoneIP=$(echo "${IP}" | awk -F '.' '{print $1"."$2"."$3}')
          RZIP=$(echo "${rzoneip}" | awk -F '.' '{print $3"."$2"."$1}')
          IP2add=$(echo "${IP}" | awk -F '.' '{print $4}')
          ;;
       *) # should never happen
          exit 1
          ;;
   esac

Thanks,
