Block URL
This feature allows you to block access to undesirable Web sites. You can block by URL, IP address,
or Keyword. You can also have different blocking settings for different groups of PCs.
• In operation, every URL is searched to see if it matches or contains any of the URLs or keywords
entered here. Then, after a DNS lookup, it determines the IP address of the requested site and
checks it against IP address entries on this screen.
• Note that a single IP address may host many Web sites (shared IP). Entering an IP address on
this screen will block all Web sites that may be hosted on that IP address.
