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 periodic router advertisement messages. These messages contain one
or more IPv6 prefix options, and they can specify 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 is useful 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 to use the DHCPv6 server for stateful configuration. You can
select one of the following DHCPv6 policies for the print server to use:
●
Under router control Use DHCPv6 stateful configuration when requested by the router.
●
Stateless configuration fails or is disabled Use DHCPv6 stateful configuration if stateless
configuration fails or is disabled.
●
Always use DHCPv6 On startup, always use DHCPv6 for stateful configuration.
Stateful configuration is useful when host configuration beyond that provided by a router is necessary,
such as a domain name or DNS server addresses.
Use DNS
HP Jetdirect print servers support the configuration of IPv6 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 can be cumbersome. Some client applications might not support the direct IPv6
address entry. However, name resolution can be available for the print server if 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.
NOTE: The print server does not support dynamic updates to DNS. IPv6 addresses are not
automatically supplied to DNS servers.
