Stateless Addresses; Stateful Addresses; Using Dns - HP 635n - JetDirect IPv6/IPsec Print Server Administrator's Manual

Stateless Addresses

Stateless addresses are usually assigned to the print server under router control, and not by a server
(such as a DHCPv6 server). However, the router can specify that other configuration be provided by
a server.
The print server must receive Router Advertisement messages which are periodically sent by a
router. These messages, among other things, contain one or more IPv6 prefix options (for example,
specifying 64–bit local subnets, or a default route). These prefixes are combined with a 64-bit host
address (derived from the print server's MAC address) to form the IPv6 stateless addresses
configured on the print server.
Stateless addressing may be preferred for networks that require traffic to be routed but with minimal
network configuration.

Stateful Addresses

A DHCPv6 server configures stateful IPv6 addresses on HP Jetdirect print servers. A DHCPv6 policy
on the print server determines when a DHCPv6 server is to be used for stateful configuration. You
can select one of the following DHCPv6 policies for the print server to use:
■ Under router control: (default) DHCPv6 stateful configuration will be used when requested by
the router.
■ Stateless configuration fails: Use DHCPv6 stateful configuration if stateless configuration fails.
■ Always use DHCPv6: On startup, always use DHCPv6 for stateful configuration.
Stateful configuration is useful when host configuration beyond what a router can provide is
necessary (such as a domain name or DNS server addresses).

Using DNS

HP Jetdirect print servers support the configuration of IPv6 Domain Name System (DNS) servers for
the print server.
Due to IPv6 address length and complexity, specifying an IPv6 address in applications to identify or
search for a device may be cumbersome. Some client applications may not even support the direct
entry of an IPv6 address. However, name resolution may be available for the print server provided
the appropriate IPv6 records are configured in DNS. If name resolution is supported, you can enter
the print server's host name or a fully qualified domain name (FQDN) when using these applications.
