How to block a Domain
No domains are blocked by default (except phishing sites!), but it’s easy to block a domain, such as porn sites, malicious websites (virus etc) or any website that you don’t want to get accessed on your computer. This is a great tutorial on how to block a Domain.
1. Make sure you are using OpenDNS.
2. Sign in or create a free account.
3. Add a network to your account in the Dashboard.
If you already have a network in your OpenDNS account, you may skip this step.
Add a single IP address or a range of addresses to create a network. OpenDNS supports dynamic IP addresses, common for cable, DSL, and dial-up customers.
4. Add a domain to block
From the Networks page, click on the wrench icon () to edit Settings for that network. (Or click on the Settings tab in the Dashboard and navigate to the appropriate network.)
Click Block Domains on the left-hand side navigation.
Enter the domain(s) you want to block on that network (Winzipices.cn). Choose whether this block should apply to all networks, if you have more than one.
5. Wait 3 minutes for your preferences to be pushed to all servers.
You may then test by attempting to visit the site you blocked. Make sure any local caches (browser, computer, router, firewall, etc.) are cleared before you test. Review this checklist if you think it’s not working.
Turn on content filtering for your network(s).
From the Networks page, click on the wrench icon () to edit Settings for that network. Or click on the Settings tab in the Dashboard and navigate to the appropriate network. From the Settings page, the Category Blocking page is where you make your choices. (Choose Adware)
Check the box for each category you would like to block, then Save.
5. Wait 3 minutes for your preferences to be pushed to all servers.
You may need to clear your local resolver cache if the domain has been visited recently, which is often the case when you start to block new categories.
