However, in practice, blocking URLs is unreliable, mainly because URLs are typically blocked by proxy servers as full-text URLs. The simple proxy server 1st Up Net Server (formerly NetProxy), for example, lets you enter the URLs of sites that you want to block from passing through the WWW proxy gateway. However, if you only enter the domain name of the site, users can still access the site using the IP address that corresponds to the URL. Security policy is a more effective method of preventing employees from visiting certain Web sites, because URLs could easily be changed.
