Thats ok, no need to be sorry. Basically by changing the DNS service used by the network, you can manage what sites are visited in terms of content, and you are able to add specific websites you want opendns to block.
Here is a rough guide on how to set up open and set up OpenDNS.
1. Create an OpenDNS account
here
2. Register Account (they will send you a email which you need to accept to activate account)
3. Add your Network
To do this, firstly sign in.
Then go to the dashboard page.
Then go to the settings tab. There will be an option to add a network.
This will allow you to manage the settings for that specific network, there will be a tab at the top of the screen and it will say " Your current ip is: xxx.xxx.xxx.xxx" (obviously there will be numbers in there).
This is the network address you will need to add to the space provided.
You will then be prompted with a page with the following questions
Give it a friendly name: Something simple like "Office" or "Home" will do.
Call it whatever you desire.
Is this a dynamic IP address? What is a dynamic IP address?
Your IP address is most likely dynamic, so select yes.
Download the software and stay safe. The OpenDNS Updater software ensures that your OpenDNS preferences are preserved whenever your IP address changes.
It is a good idea to download this software, just in case.
4. Manage Settings
Once this is done you have successfully added your network, now it is time to manage the settings.
You will see your added network under the Your networks Sub-Heading. Click the ip address to manage the settings.
You will then see Web Content Filtering preferences page, this is where you can specify the level of filtering. Choose the level you desire from the following:
High
Protects against all adult-related sites, illegal activity, social networking sites, video sharing sites, and general time-wasters.
26 categories in this group - View - Customize
Moderate
Protects against all adult-related sites and illegal activity.
13 categories in this group - View - Customize
Low
Protects against pornography.
4 categories in this group - View - Customize
None
Nothing blocked.
Custom
Choose the categories you want to block.
You can also choose to Manage individual domains, add a domain eg.(www . example . com) into the field and click add domain.
Once you have all your filtering settings added you can change your DNS servers locally.
5. Add DNS servers locally
This can be done locally, either by changing the DNS server addresses in the router, or on the specific computer.
To change the IP address on the router, log into the router and change to DNS server addresses to:
Primary:208.67.222.222
Alternate:208.67.220.220
Alternatively you can change it on the local computer, it is located in the Connection properties for the adapter connecting to the internet.
If you need me to be a bit more specific about some things i'm am happy to do that.
Let me know how you go.
