Barracuda Web Filter - All Firmware Versions

There are several reasons why you would need to block or exempt a site. See Solution 00004277 for information about adding exemptions. Before you can block or exempt a website IP address, you need to find out what that IP address is. There are several ways to find out this information.

1. You can use the web filter troubleshooting tools to find out this information. See Solution 00006350 for information on using the Web Filter troubleshooting tools.

2. You can ping the site at the command line and the ip address will be returned in the echo reply.

Pinging [] with 32 bytes of data:

3. You can also use the nslookup tool on the windows command line.




Non-authoritative answer:


Addresses: 2607:f8b0:4005:800::1002

Additional notes:
For one third party app you can use.
If you use Chrome at all, there is an add-on extension called "IP address and domain information"
This will usually give full details of the whole site you go to.
Load site and then click the extensions ICON for details. It should be located after the URL field of your browser.
It uses to gather all details it can on the site and shows the range of IPs used etc for a more extensive list of IPs found.
Example: opened site and see this as their range used.
IP-range/subnet -
While only an nslookup showed me this IP alone.
This is not a barracuda supported service.
