It is not sufficient to merely add the utilization field to the serializer, or this would have already been done. As it stands, your change would effect a new database query to fetch all the IP addresses for each individual IP range returned in an API response. (Take a look at the utilization property defined on the IPRange mode.) This would substantially degrade performance.
This is somewhat similar to #7845, but might be doable by annotating the count of IP addresses for each range on the queryset. @icovada would you like to own that work?
