Go to Administration → System Settings → Network.
The following format rules apply to Deep Discovery Inspector network settings.

Network Setting Format Rules

Format Setting
Description
Appliance Host Name Format
The host name can contain alphanumeric characters and dashes ("A-Z", "a-z", "0-9", "-").
Dynamic IP Address
Obtain a dynamic IP address from a DHCP server on your network. Verify that the Preconfiguration Console has been changed accordingly. For details, see the Deep Discovery Inspector 5.8 Installation and Deployment Guide.
Static IP Address Format
Note
Note
The IP address cannot be the broadcast or network address.
IP addresses must be in the format: XXX.XXX.XXX.XXX, where X is a decimal value between 0 and 255.
The IPv4 address cannot be in any of the following formats:
  • AAA.XXX.XXX.XXX, where AAA is in the range 223 to 240 [Multicast Address]
  • 0.0.0.0 [Local Host name]
  • 255.255.255.255 [Broadcast Address]
  • 127.0.0.1 [Loopback Address]
The IPv6 address cannot be in any of the following formats:
  • ff00::/8 [Multicast Address]
  • fe80::/10 [Link-local Address]
  • ::0 [Unicast route Address]
  • ::1/128 [Loopback Address]
Subnet Mask Format
Note
Note
The subnet mask cannot be the broadcast or network address.
The binary format of a subnet mask starts with a sequence of continuous 1s and ends with a sequence of continuous 0s.
IPv4 address subnet mask example:
  • For 255.255.255.0, the binary format is 11111111.11111111.11111111.00000000.
Subnet Prefix Format
IPv6 addresses convert groups of bits into groups of hexadecimal digits, separated by colons. The high-order bits on the left of an IPv6 address specify the network, the rest specify particular addresses in that network. All the addresses in one network have the same first N bits, called the "prefix".
Use "/N" to denote a prefix N bits long.
IPv6 address subnet prefix example:
  • For 2001:db8::/32, the prefix is /32 and is 32 bits long.
This example means all addresses where the first 32 bits are 2001:db8.
Default Gateway Address Format
The gateway must be in the same subnet as the IP address.
