Luckily, glibc has a way to disable DNS queries without LD_PRELOAD trickery:
$ RES_OPTIONS=attempts:0 wget http://www.example.com/
Wow, I wonder many people have used this innocent environment variable name
and been bitten by weird network failures..
The name is not great, but it's been like that at least since 1995. It's not
going to be changed.
Couldn't they at least call it LIBC_RES_OPTIONS?
codesearch.d.n tells me this variable in not (g)libc-specific. There are other
resolvers that honour it, too.
