When 

, you must provide one or 

more network addresses, whether for a Local Custom Category, or in an External Live Feed Category 
feed file. In each instance, you can enter multiple addresses separated by line breaks or commas. These 
addresses can be in any of the following formats:

IPv4 address, such as 10.1.1.0

IPv6 address, such as 2001:0db8::

IPv4 CIDR address, such as 10.1.1.0/24

IPv6 CIDR address, such as 2001:0db8::/32

Domain name, such as example.com

Hostname, such as crm.example.com

Partial hostname, such as .example.com; this will also match www.example.com

Regular expressions to specify multiple addresses that match the provided patterns (see 

 for more information about using regular expressions)

It is possible to use the same address in multiple custom URL categories, but the order in which 
the categories are listed is relevant. If you include these categories in the same policy, and define 
different actions for each, the action defined for the category listed highest in the custom URL 
categories table will be the one applied.

If you select External Live Feed Category for the Category Type when 

, you must select the feed format (Cisco Feed Format or Office 365 

Feed Format) and then provide a URL to the appropriate feed-file server. 

The expected format for each feed file is as follows:

Cisco Feed Format – This must be a comma-separated values (.csv) file; that is, a text file with a 

.csv

 extension. Each entry in the .csv file must be on a separate line, formatted as 

address/comma/addresstype (for example: 

www.cisco.com,site

 or 

ad2.*\.com,regex

). Valid 

addresstypes are 

site

 and 

regex

. Here is an excerpt from a Cisco Feed Format .csv file:

www.cisco.com,site

\.xyz,regex

ad2.*\.com,regex

www.trafficholder.com,site

2000:1:1:11:1:1::200,site
