Vendor and Site Specific DHCP Options Reference Manual (MGCP/NCS Version)

Please refer to your DHCP server’s documentation to learn how to create site specific information. See
“Entering IP Addresses” on page 55 for more details on the syntax to use.
Option Codes
This table lists all vendor specific sub-option codes.
Entering IP Addresses
In the DHCP server, IP addresses can be entered in decimal, hexadecimal or octal format. See “IP Addresses”
on page 41 for more details.
There are two formats of address string:
Long: Has a size of 6 bytes (12 hexadecimal characters) and includes the IP address and port.
Short: Has a size of 4 bytes (8 hexadecimal characters) and includes only the IP address. In
this case, the default port is used.
Numeric values are stored in network byte order (Big-Endian).
When entering IP addresses in the DHCP server, there is a difference between the vendor specific option and
the site specific option.
The vendor specific options must be encapsulated because more than one information can be stored in this
option:
[code][length][4-6 bytes address][another code][another length][another
address]...
The site specific options can have only one information per option:
[4-6 bytes address]
