You might know (or if you are a Comcast customer experienced first hand) that last night for about 2 and a half hours Comcast customers in New England and Washington D.C. experienced an outage of their internet services. Luckily the problem is solved now and it turned out to be not an outage “per se” but a DNS issue, easily solved if you knew how to set a new DNS server address in your router. One possibility to consider if something like this will ever happen to you is OpenDNS that provides four IP addresses that you can use and it might even improve your existing internet service offering faster resolution. (What a DNS service does is to offer a translation between a friendly web address, for example cnn.com and its real IP address – 188.8.131.52).
The following are the 4 addresses that you can use, from Open DNS.
- 184.108.40.206 (resolver1.opendns.com)
- 220.127.116.11 (resolver2.opendns.com)
