The IP Touch 40x8EE phone is compatible with any DHCP server that correctly supports 
the BOOTP server IP address - siaddr (also called ‘next-server’) field. See standard RFC 
951 for further information. 
The syntax for the ‘Option’ 43 IP is as follows: 
 
<opcode> <length> <IP> 
<opcode> = 0x40 (64 decimal) 
<length> = 0x04 (4 decimal) 
<IP> = IP Address in hexadecimal – e.g. for 192.168.1.30 content should be (0xC0 A8 01 1E)
