order deny,allow

forward slash range multiplier what does this do

[WiseWombat]

Hi all This is my first post and Im haveing problems with chiness and korean Ip networks.

I have set my httpd.config as

order deny,allow
deny from 203.218.
deny from 203.177.

This has probably been asked lots of times But Could some one explain to me what a forward slash range multiplier at the end of a full ip address means as I am new to apache.

deny from 203.218.0.0/?

The full ip ranges are displayed as

203.218.0.0 - 203.218.255.255
203.177.96.0 - 203.177.127.255

Thanks in advance

Depends on what's after the /

For info on things like /28, google on 'cidr notation'
For info on things like /255.255.255.128, google on 'subnet masks'

(although 'subnet masks' would be a good thing to search on in either case).
