HP ew2500 802.11b/g Print Server manual TCP/IP configuration, IPv6 configuration

3 TCP/IP configuration

To operate properly on a TCP/IP network, you must configure the HP Jetdirect print server with valid TCP/IP network configuration parameters, such as an IP address that is valid for your network.

The HP Jetdirect print server supports both IPv4 and IPv6 networks simultaneously. Print server configuration for IPv4 operation remains the same as in previous HP Jetdirect products.

IPv6 configuration

HP Jetdirect print servers provide basic configuration capabilities for operation on an IPv6 network. For IPv6 printing services, the print server supports the following:

●IP printing (raw) using HP-proprietary TCP port 9100

●LPD printing using standard TCP port 515

●IPP printing using standard TCP port 631

●FTP printing using standard TCP ports 20 and 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

In the example, h is a hexadecimal digit 1 through 0, A through F. This is sometimes called colon

hexadecimal format.

Depending on the application, you can enter or display an IPv6 address using a shortened version when successive fields contain all zeros (0). You can use two colons (::) and omit leading zeros in a field. (The use of two colons to represent successive zero fields can be used only once in an address.) The following is an example IPv6 address:

2001:0DB8:0000:0000:0000:0000:0200:bb02

Using the shortened version, the example address is:

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
