Does permit/deny have any influence on registration, or is it related

How do you stop an asterisk server from accepting registrations when
the IP is outside a subnet even if the username and secret are
When host=dynamic registrations are accepted even if the pemit IP is
different from the registered device's IP address. Does permit/deny
work on a single IP address eg 192.168.4.111/255.255.255.2555
The same seems to apply in the [general] section, with contactdeny and
