Most users will not have a need to target specific system level criteria, however
for those that do we provide the following.

In Targeting section select Advanced tab.. n. Click OK.

The following tabs are available:
Rules that are used on IP-addresses, User Agents, Page URLs, Referral Pages, Page variables are of 2 types:
- Permissive - Equal, Contain, Regular Expression, More than, Less than
- Prohibitive - Not Equal, Doesn't Contain, Not a regular expression.
Among permissive rules OR logics is applied.
Among prohibitive rules AND logics is applied.

You can target your ad campaign on visitors who use certain browsers by moving browsers names from Allowed list to Forbidden and backwards.
For example, if you advertiser widgets for Internet Explorer you will probably want to display your advertisement for IE users only. Thus you'll move all browsers except Internet Explorer to the Forbidden list.


You can target your ad campaign on visitors who use certain operating system by moving OS names from Allowed list to Forbidden and backwards.
For example, if you advertise software that works in Windows OS only, you will want to display it only for those visitors who use Windows. Thus you'll have to move all OS except Windows to the Forbidden list.

On this tab you can target ads delivery to visitors coming from certain IP-addresses by setting special rules.
These rules are:
- Equal
You can allow ads displaying for an exact IP-address.
For example, allow ads delivery for "123.45.67.8" IP-address.
- Not equal
You can filter out a certain IP-address.
For example, if you set Not equal rule for "123.45.67.8", ads will be delivered for all visitors except "123.45.67.8".
- Contain
You can allow all IP-addresses that contain defined value.
For example, if you define "123.45", ads delivery for the following IP-addresses will be allowed: "123.45.7.8", "8.123.45.7", "7.8.123.45", etc.
- Doesn't contain
You can filter out IP-addresses that doesn't contain defined value.
For example, if you define "123", IP-addresses that contain it won't be allowed, like "123.56.98.45", "25.35.123.5", "45.89.23.123", etc.
- Regular expression *
You can set a regular expression that will define what IP-addresses should be allowed. In regular expressions you can use:
^ - matches the starting position within the string
$ - matches the ending position of the string
* - matches the preceding element 0 or more times
+ - matches the preceding element 1 or more times
For example, regular expression "^12+" allows all IP-addresses starting with "12": the range of 12.0.0.0 - 12.255.255.255.
- Not a regular expression *
You can filter out all IP-addresses that fit to a regular expression.
For example, if you define regular expression "^192.168+", ads won't be delivered to 192.168.0.0 - 192.168.255.255 IP-addresses.
