HP 640n Print Server manual 5TCP/IP Network Identification tab

Table 4-4TCP/IP Summary tab (continued)

Item	Description
IPv6 Address list	IPv6 addresses configured on the print server. For each address, the following items
	are specified:
	●	Prefix length: Number of bits that comprise the fixed portion of the address.
		Typically, it is 64 and identifies network/subnet portion of the address.
	●	Config By: How the address was configured, such as auto-configuration
		through link-local addressing, by a router, by a DHCP(v6) server, or configured
		manually.
	●	Valid Lifetime: Length of time (lifetime) that the address can be used, after
		which the address becomes invalid. Determined during the auto-configuration
		process.
	●	Preferred Lifetime: Length of time (lifetime) that the address can be used
		without limitation. After this time, the address is deprecated (its use is
		discouraged). The preferred lifetime is a subset of the valid lifetime, and is
		determined during the auto-configuration process.
Default Route Information	IPv6 address and the length of time until it expires. (Used when a router advertises
	itself to the print server as a default router on the local link.)

Network Identification tab

This tab provides TCP/IP network identification. Items on this page are described in the following table.

NOTE: Names, such as host and domain, must begin with a letter and can contain only letters, numbers, periods (for domain names only), or hyphens. The underline character (_) is not allowed.

Table 4-5TCP/IP Network Identification tab

Item	Description
Host Name	Readable IP name (the SNMP SysName object) for the network device. Must start
	with a letter and can end in a letter or number, and be up to 32 ASCII characters in
	length. The default name is NPIxxxxxx, where xxxxxx are the last six digits of the LAN
	hardware (MAC) address.
Domain Name (IPv4/IPv6)	DNS domain name that the HP Jetdirect print server resides in (for example,
Domain Name (IPv6 only)	support.hp.com). This name is not the host name or the FQDN (such as
	printer1.support.hp.com).
	The IPv4 and IPv6 domain names can be the same or different depending on the
	network. A separate IPv6 domain name can be assigned on networks where
	segmentation of IPv4 and IPv6 hosts is desirable. If you assign an IPv6 domain name,
	it applies to the IPv6 network only.
DNS (IPv4)	Primary and secondary DNS servers on your IPv4 or IPv6 networks.
DNS (IPv6)	Primary: IP address of the primary DNS server.
	Secondary: IP address of a secondary DNS server to use if the primary DNS server is
	unavailable.
