TCP/IP Configuration

To operate properly on a TCP/IP network, the HP Jetdirect print server must be configured with valid
TCP/IP network configuration parameters, such as an IP address that is valid for your network.
HP Jetdirect print server supports both IPv4 and IPv6 networks simultaneously. Print server
configuration for IPv4 operation remains the same as prior Jetdirect products.

IPv6 Configuration

HP Jetdirect print servers provide basic configuration capabilities for operation on an Internet Protocol
version 6 (IPv6) network. For IPv6 printing services, the print server supports raw IP printing (through
HP-proprietary TCP port 9100), LPD printing (through standard TCP port 515), IPP printing (through
standard TCP port 631), and FTP printing (through standard TCP ports 20, 21).
The print server supports remote configuration by DHCPv6 servers and IPv6 routers. In addition, it
supports remote configuration and management from a Web browser over HTTP or HTTPS. Local
configuration of basic IPv6 parameters is available through the printer control panel if supported by the
printer/MFP device.

IPv6 Address Introduction

An IPv6 address consists of 128 bits. The normal format of an IPv6 address is eight fields, each
separated by a colon (:). Each field contains four hexadecimal digits representing 16 bits:
hhhh:hhhh:hhhh:hhhh:hhhh:hhhh:hhhh:hhhh
where h is a hexadecimal digit 1 through 0, A through F. This is sometimes called colon hexadecimal
format.
Depending on the application, an IPv6 address may be entered or displayed using a shortened version
when successive fields contain all zeros (0). In this case, two colons (::) are used. In addition, leading
zeros in a field can be omitted. For example, the following IPv6 address:
2001:0DB8:0000:0000:0000:0000:0200:bb02
may be entered or displayed as
2001:DB8::200:bb02
However, the use of two colons to represent successive zero fields can be used only once in an address.
IPv6 addresses are often specified by a prefix that identifies a fixed value associated with the first part
of the address, followed by a prefix length that specifies the number of bits in the prefix. In IPv6
addressing, a prefix length of 64 is typically used to specify a network or subnet. A prefix with a prefix
length less than 64 typically identifies a portion of the IPv6 address space or a route.
