I have commented on this service before, but a podcast reminded me of what the service offers and I decided to promote the site again. OpenDNS<\/a> is a filtering service that takes advantage of DNS. The domain name service you use converts a URL (a web address) to a the ip address that computers use to communicate (the series of four numbers separated by periods). You probably use a DNS provided by your service provider, but you can use other DNS servers. This is how OpenDNS works – you substitute it for the default.<\/p>\n

When you use OpenDNS, the service can block (filter) your access to web sites. You might want to do this to avoid known phishing sites or to prevent children using your computer from viewing content you feel is objectionable. You have several ways of controlling what sites will be blocked. If you do nothing else, blocking phishing and some malware sites is worth the effort.\u00a0This is a free service for home users.<\/p>\n

\"\"<\/a><\/p>\n

One challenge in using this service is asking your system to use the DNS assigned by OpenDNS rather than the default. On a Mac, you open the network preference option from system preferences, select DNS and then enter the IP number provided by OpenDNS.<\/p>\n
