I am trying to block access to a single IP address by adding a specific route that leads "nowhere" (instead of the default gateway):
route ADD 126.96.36.199 MASK 255.255.255.255 127.0.0.1 METRIC 10
The problem is that this command fails with the following error:
The route addition failed: The parameter is incorrect.
It doesn't say which parameter is incorrect. I probably violated an implied rule of networking basics but I don't know what it is. Any idea which parameter is incorrect and, more importantly, why?
