said by margaf:said by bohratom:Better to select IP Network 206.111.0.0 with a subnet of 255.255.0.0 as it will use less memory in the routing table then having multiple IP's entered. Of course if this is the only network you are blocking then memory will not be an issue and more directed to users that have alot of IP's being blocked.
This was what I did and so far I notice vast improvement on youtube.
I tried blocking both 206.11.0.0/16 and 173.194.55.0/24 and still hit or miss on the transfer speeds. Hopefully someone will have more slow google caching servers to add to the block.
