IP calculator tool: supports IPv6 and IPv4 networks. For list of values see below.
IP list is optional since it will return many IPs for some subnets,
if you need to show ip list you will have to append ``?iplist`` to your get request.
**PLEASE NOTE:** iplist will print only 65536 addresses which is /16 in IPv4 subnetting or /112 in IPv6 subnetting.
If you try to get more you will get an error.
:param query: IP address or hostname
:param netmask: (Optional) If you want the whole range of hosts
**Example:**
When getting single host
