    IPv4 example: 192.168.1.0/24
    IPv6 example: fd00:1:1111:200::1000/116
Maximum IP Address Entities
Add up to 10,000 Deny / Allow List IP Address entities.
Domain
Supported Characters
Each domain name must have at least one character.
Deep Discovery Inspector supports the following characters for domain names:
ASCII
  • 0x2D (-), 0x2E (.)
  • 0x30 (0) ~ 0x39 (9)
  • 0x41 (A) ~ 0x5A (Z)
  • 0x61 (a) ~ 0x7A (z)
UTF-8 characters (ASCII code >=0x80)
Note
Note
Convert non-UTF8 characters to Punycode.
Maximum Length
Maximum length of each domain name: 63 characters
Maximum length of domain: 255 characters
Wildcards (*)
Wildcards are only allowed in a prefix. When a wildcard is used in a prefix, it must be connected with ". ". Only one wildcard may be used in a domain.
Domain matching is case-sensitive.
Maximum Domain Entities
Add up to 10,000 Deny List / Allow List Domain entities.
URL
Syntax
[http:// | https://]<Domain>[:<Port>][/<URI-prefix>]
  • [http:// | https://]
    If unassigned, the default is "http://".
    To match both "http://:" and "https://", create multiple rules.
  • <Domain>
    Follow the syntax of Domain deny list for DNS.
  • [:<Port>]
    (Optional) If unassigned, the default is ":80" (port 80) for HTTP or ":443" (port 443) for HTTPS.
    Assign a specific port with a whole number between 1 and 65,535, or use a wildcard (*) to assign all ports.
  • [/<URI-prefix>]
    (Optional) If unassigned, the default is a wildcard that matches all paths.
    Use "/" and "/*" to match a URL without a path.
    Example: www.abc.com/* matches www.abc.com
    [/<URI-prefix>] is always applied as a prefix matching. Only one wildcard is accepted in a prefix.
    URI matching is not case-sensitive.
Maximum URL Entities
Add up to 10,000 Deny / Allow List URL entities.

  • 0x41 (A) ~ 0x46 (F)
  • 0x61 (a) ~ 0x66 (f)
Maximum Length
Maximum length of a SHA-1 rule: 40
Maximum SHA-1 Entities
