For example:
• 2001:DB8:1234:215:215:99FF:FE04:D345 / 128 is used to reference a complete 
address. 
• 2001:DB8:1234:215:215:99FF:FE04:D345 / 64 is used to reference prefix 
address consisted of leftmost 64 bits only. 
• 2001:DB8:1234:215:215:99FF:: / 80 is used to reference prefix address consisted 
of leftmost 80 bits only.

IP Sec
IP Sec (IP Security) is comprised of the IP Authentication Header and IP Encapsulating 
Security Payload protocols, that secure IP communications at the network layer of the 
protocol stack, using both authentication and data encryption techniques. The ability to 
send IP Sec encrypted data to the printer is provided by the use of a public cryptographic 
key, following a network negotiating session between the initiator (client workstation) and 
the responder (printer or server). To send encrypted data to the printer, the workstation and 
the printer have to establish a Security Association with each other by verifying a matching 
password (shared secret) to each other. If this authentication is successful, a session public 
key will be used to send IP Sec encrypted data over the TCP/IP network to the printer. 
Providing additional security in the negotiating process, SSL (Secure Sockets Layer 
protocols) are used to assure the identities of the communicating parties with digital 
signatures (individualized checksums verifying data integrity), precluding password 
guessing by network sniffers.
Enable IP Sec
This procedure requires that you have a Shared Secret available.
IP Sec cannot be enabled until SSL (Secure Sockets Layer) is enabled on the machine.
1. At your Workstation, open your Web browser and enter the TCP/IP Address of the 
machine in the Address bar.
2. Press [Enter].
3. Click on the [Properties] tab.
4. Click on the [Security] link.
5. Select the [IP Sec] in the directory tree.
6. Enable the Protocol by placing a checkmark in the [Enabled] box.
7. Enter the a password in the [Shared Secret] and [Verify Shared Secret] boxes.
8. Checkmark [Select to save new Shared Secret] box.
9. Click on the [Apply] to save settings.
