I am looking for a good reference to explain how to ALLOW access by IP. Specifically, I need to know how to enter the IP address as well as address ranges.

I think x.x.x.3-10 won't work if I want to allow

x.x.x.3
x.x.x.4
x.x.x.5
...
x.x.x.10

have you seen
http://httpd.apache.org/docs/mod/mod_access.html

it doesn't talk about the 3-10 thing..
I don't think that will work then.

I can't try it in my network

Nice link Allowee. This is also a good place for .htaccess information: http://javascriptkit.com/howto/htaccess.shtml

they don't give me a clue as to why the following works only partially.

Here is the .htaccess file

AuthUserFile /home/hydroweb/.htpasswd
AuthGroupFile /dev/null
AuthName "Journal of Environmental Hydrology"
AuthType Basic

<limit GET>
satisfy any
order deny,allow
deny from all
allow from 63.76.22.2
allow from 130.116.16.
allow from 130.116.17.
allow from 130.116.18.
allow from 130.116.19.
allow from 144.110.16.
allow from 144.110.17.
allow from 144.110.18.
allow from 144.110.19.
allow from 140.253.201.
allow from 152.83.56.
allow from 152.83.57.
allow from 152.83.58.
allow from 152.83.59.
allow from 152.83.176.
allow from 152.83.177.
allow from 152.83.178.
allow from 152.83.179.
allow from 144.110.36.
require valid-user
</limit>

Some of the IPs can get access, some can't.

Maybe the problem is that the client's IP (the one they give me for my allow from list) is not what my site sees when they try to gain access?

Thanks in advance.
