DNS interception. TWC does the same thing, as other ISP's do.

I don't use my ISP's DNS server. TWC not only does interception on DNS 
queries but also had a lot of DNS outages for me years ago. Easier to just 
run bind on a local linux box. That way I never have to worry about this 
sort of shenanigans.

Also gives you the advantage of being able to blackhole any specific zones 
you want for your entire home network (i.e. known malware subnets, 
advertising networks, whatever)
