Description

Hi.
A similar issue #1390 was submitted already, but it was for a "list" method.
Trying to provision an IPv6 address from a /64 subnet using the API:

curl -v -X POST -H "Authorization: Token XXXXXXXXXXX" \
-H "Content-Type: application/json" \
-H "Accept: application/json; indent=4" \
'https://netbox.example.com/api/ipam/prefixes/301/available-ips/?limit=1' \
-d '{"description":"ipv6 description"}'

NetBox replies:

exceptions.IndexError
range contains more than 9223372036854775807 (sys.maxint) IP addresses!Use the .size property instead.

Thanks.
