Free list Of Public DNS Servers

Updated List of Publicly Available and Completely Free DNS Servers

 Most of the time, your ISP automatically assigns a primary and secondary DNS server when your router or computer requests network information via DHCP.

But what if those ISP-provided DNS servers aren't working properly or they block certain sites?
Luckily there are several free DNS servers that you can use instead of the ones assigned to you, the most popular and reliable of which you can find below.

See How Do I Change DNS Servers? for help if you're not sure what to do.

<sub>[1] The DNS servers listed above as Level3 will automatically route to the nearest DNS server operated by Level3 Communications, the company that provides most of the ISPs in the US their access to the Internet backbone.

Note: Primary DNS servers are sometimes called preferred DNS servers and secondary DNS servers are sometimes called alternate DNS servers. Primary and secondary DNS servers can be "mixed and matched" to provide another layer of redundancy.</sub>
