This may have negative ramifications for Charter as news of this
unethical activity gets out:
As of yesterday (as best I can determine), Charter.net cable internet
services is now hijacking bad DNS queries. In other words, if you
mistype a domain name and end up typing one that doesn't exist,
normally you'd get an error message. Your own browser has settings
where you can choose to be redirected to a search page of your choice,
or none at all, if that is your choice.
Charter took that choice away. Now, all bad queries go to here:
http://ww11.charter.net/search
It doesn't matter what your browser settings are. This is because
your browser depends on an error code coming back from the Domain Name
Servers (DNS), at which point your browser would either display an
error message or redirect you to your chosen search page. Now, since
Charter's DNS servers never return errors and instead respond with
Charter's search page, your browser never receives the proper error
code and therefore has no trigger to take you to your chosen search
page.
This presents further problems as many software applications (off the
shelf and custom, and enterprise software) depend on the internet
working the same everywhere. Many applications depend on this error
code. They will all fail to work as designed because Charter wants to
make advertising revenue.
This unethical activity was attempted by Verisign back in 2003 (but in
their case, it effected the ENTIRE internet, not just customers of a
single ISP). You can get more information on the Verisign fiasco here
for context:

Yes, but that requires a cookie. Browsers use cookies, but not all
software that depend on DNS use cookies.
It should work according to expected standards by default. Other ways of
things working should be opt-in, not opt-out, especially if the opt-out
doesn't do the job it's supposed to.
