IP restrictions, How does AuthHosts Work?

AuthHosts
The AuthHosts setting is, unlike the other settings, a REG_SZ string. It is used to specify a set of IP address templates which incoming connections must match in order to be accepted. By default, the template is empty and connections from all hosts are accepted. The template is of the form:
+[ip-address-template]
?[ip-address-template]
-[ip-address-template]
In the above, [ip-address-template] represents the leftmost bytes of the desired stringified IP-address. For example, +192.168 would match both 192.168.12.10 and 192.168.14.2. Multiple match terms may be specified, delimited by the ":" character. Terms appearing later in the template take precedence over earlier ones. e.g. -:+192.168: would filter out all incoming connections except those beginning with 192.168. Terms beginning with the "?" character are treated by default as indicating hosts from whom connections must be accepted at the server side via a dialog box. The QuerySetting option determines the precise behaviour of the three AuthHosts options. Local machine-specific setting.

ultravnc 1.0.3 and above via ultravnc.ini (not registry)

AuthHosts=
+ =allow
- = deny
? = query
syntax:
-:+10.0.60.141:?10.0.31.169:-10.0.20.240:
instead of 10.0.60.141 you can use 10.0.60, then it is valid
for the full range of ip addresses.
QuerySetting=2
Define on how to react on the (-,?,+) from
the Authhosts.
0="+:Accept, ?:Accept, -:Query"
1="+:Accept, ?:Accept, -:Reject"
2="+:Accept, ?:Query, -:Reject [Default]"
3="+:Query, ?:Query, -:Reject"
4="+:Query, ?:Reject, -:Reject"
It is used to specify a set of IP address templates
which incoming connections must match in order to be accepted.
By default, the template is empty and connections from all
AuthHosts_Tip5="hosts are accepted. The template is of the form:
+[ip-address-template]
?[ip-address-template]
-[ip-address-template]
In the above, [ip-address-template] represents the leftmost
bytes of the desired stringified IP-address.
For example, +158.97 would match both 158.97.12.10 and
158.97.14.2. Multiple match terms may be specified, delimited
by the ":" character. Terms appearing later in the template
take precedence over earlier ones. e.g. -:+158.97: would filter
out all incoming connections except those beginning with 158.97.
Terms beginning with the "?" character are treated by default as
indicating hosts from whom connections must be accepted at the
server side via a dialog box. The QuerySetting option determines
the precise behaviour of the three AuthHosts options.
