I don't know, but it probably is comparable to what it would take to 
put them in the firewall rules.

netstat -nr|grep 127

The way I use  it is a single IP, but a quick read of the man page it 
seems you can also indicate blocks. Man route and search for the phrase 
"For example"

Also see my other poston this thread. In particular the URL to the small 
scripts I use. They could use lots of improvement, but they may be a good 
start for someone interested in automating the process.

I believe there are also programs which can monitor the logs and 
automatically perform actions, but those are likely harder to learn and 
setup.
