Static versus Dynamic IPs

Post by Barrie Morgan » Sat Feb 19, 2011 1:58 pm

I develop online tests and want to restrict access only to students logging in at their college campus.
My client says his IP is dynamic yet it has not changed in over one year.
Is this possible?
If I specify his IP, say, 123.456.*.* it could let someone in off-campus who has 123.456.*.* in their dynamic IP, and so be a security breach.

This can be easily done. Using your site's .htaccess file allow only ip ranges from the school in question and deny all others. This can be done in a matter of mere minutes.

Since my previous post, I checked this website and find my client's IP address is static after all, and not dynamic as he claimed.
That explains why they said it did not change.
For dymanic, do the first two groups 123.456....always stay the same and only the last two groups change?

Generally for a dynamic range, only the last octet will change.
