My router is latest cerowrt-3.3.8-3, installed about an hour after it hit
the ftp site.
I doubt it could got infected so fast.
Anyway, when I initially directly asked 126.96.36.199 for www.google.com it never
responded with the 42.x.y.z addresses, but some other ones. Now, after
some time, it does as well, so I'm feeling calm now.
