I notice a slight internet speed increase and fewer page not found errors when I use Google Public DNS and Open DNS instead of my ISP DNS server. I recommend changing the DNS adress for your routor, so all computers on your network use the same DNS address. If you use a laptop, then you should also change your laptop DNS address to Google’s Public DNS, Open DNS, or someother DNS service.
Google, Open DNS, and Comodo also claim that their DNS servers will protect your computer from online threats by blocking attacks.
I’m currently using Google DNS. I am very satisfied with my experience so far.
List of DNS sites.
Google Public DNS IP Address are
IP addresses 18.104.22.168 and 22.214.171.124 all you have to do is paste the IP address in your DNS settings textbox.
Google DNS is fast, safe, and reliable.
Open DNS IP addresses are
Open DNS lets you make an account, so you can block adult sites, gambling, violent, and harmful sites to all PC on your network. It also gives you a lot of statistics on your browsing activities.
Comodo Secure DNS IP addresses are
Comodo is a good DNS as well.
To change your DNS address, refer to your Routors instructional manual, or your Operating Systems instructional manual or help files in Network connections. Most of the DNS sites I listed also have very good instructional manuals for changing your DNS settings to their DNS address.
If you borrow or buy, a book on networking for your OS. You also find info on how to change your DNS settings.
Your DNS settings window should look something like this if you are using a Windows Operating System like XP, Vista, and 7.
