OpenDNS

From BE Usergroup Technotes

DNS refers to the Domain Name System, the mechanism by which a Web address is converted into a numeric computer format (called an IP address), which identifies a specific Web site server.

Internet service providers such as Be have their own DNS servers (see Be DNS servers), and others servers are available. OpenDNS is an "open source" public DNS server which performs the same function as other DNS servers, but also provides additional functionality such as optional phishing protection, content filtering, and claims of faster operation. See the www.opendns.com for more details

How to set-up OpenDNS or change DNS

OpenDNS on just your own computer (very simple to do and good for temporary tests)

To change just one computer at a time follow these instructions: https://www.opendns.com/start/computer/

OpenDNS or other DNS on all computers served by your ADSL router

To add OpenDNS server addresses on your modem, you must add the following IP address to your DNS settings in your modem:

• 208.67.222.222
• 208.67.220.220

These instructions can also be used for changing to BE's new DNS servers. Just use 87.194.255.154 instead of 208.67.222.222.

• Open Telnet and type:

open 192.168.1.254 (default modem IP address)

• When prompted for a username and password, enter:

Username: Administrator (case sensitive)
Password: <leave blank>

• First we need to check your interface name - Do the following :

{Administrator} :dns server route list

Expected result:

DNS Server       Source              Domain            Metric       Intf     State
87.194.0.51      *                                       0          RoutedEthoA  UP 
87.194.0.52      *                                       0          RoutedEthoA  UP 

(RoutedEthoA is the interface name in the above example, other customers may see "Internet" or "Static_IP" etc.)

• Flush existing DNS:

dns server route flush

• Remembering your Interface name from above, add a route to your new DNS (RoutedEthoA in the above example):

dns server route add dns=208.67.222.222 metric=1 intf=RoutedEthoA
dns server route add dns=208.67.220.220 metric=2 intf=RoutedEthoA 

• List your DNS and check if changes have taken:

{Administrator} :dns server route list

Expected result:

DNS Server       Source              Domain            Metric       Intf     State
208.67.222.222   *                                       1       RoutedEthoA     UP 
208.67.220.220   *                                       2       RoutedEthoA     UP 

• Save your settings:

saveall 

• Leave Telnet:

exit

• Test it (OpenDNS only):
