I think what you are looking for is:
acl test0 { !192.168.1.50/32; 192.168.1.0/24; };
http://jodies.de/ipcalc is a good resource for checking. (As was mentioned
by Reindl...)
Learning basic sub-netting of IP addresses (Both IPv4 and IPv6) takes time
but it's necessary for DNS configuration. There's plenty of other resources
out there. (Try googling sub-netting with or without the hyphen)
Hope that helps,
Bob
