Charter Implements SiteFinder-Like DNS
paulbiz writes "Charter Cable's DNS servers have just started resolving all invalid hostnames and pointing them to their own error page. The About page states: 'This service automatically eliminates many of the error pages you may encounter as you surf the web. No software was installed on your computer for this service to work.' It has an 'opt-out' page, but when you use it Charter simply sets a cookie that makes their page redirect errors to Microsoft Live Search instead!" One more reason to use OpenDNS, where you can actually opt out of the custom error page.
Well Charter in particular has been blocking DNS ports to anything but their DNS servers for a long time.
So running your own resolver on a Charter line probably will basically mean no DNS.
