Reasons
- Possible Speed Improvements
Third-party DNS servers COULD be faster than your ISP’s DNS servers.
- Possible Reliability Improvements
This goes hand-in-hand with the possible speed improvements above.
- Parental Controls
If you have young children and want to set up web filtering, there are a variety of different ways you can do it. One of the easiest ways to configure web filtering is to change your DNS servers to OpenDNS. Change the DNS server on your router and you’ll be able to configure parental control settings on the OpenDNS website, allowing you to block certain categories of websites and view the websites accessed from your home network.
- Security Features
Third-party DNS servers like OpenDNS and Google Public DNS also offer security features that haven’t yet been implemented by many ISP’s DNS servers. For example, Google Public DNS supports DNSSEC to ensure DNS requests are securely signed and accurate. Your ISP’s DNS servers may not yet implement such security features.
- Access Geoblocked Content
Such as what happend in Turkey. Combined with security which is important in totalitarian states or temporary situations.
