ESME_IP_ADDRESS

(string, 0 - 15 bytes) When binding to the SMPP server, the BIND PDU indicates that the client’s (that is, ESME’s) address range is an IP address. This is done by specifying a TON of 0x00 and an NPI of 0x0d. The value of the address range field is then set to be the IP address of the host running the SMS channel. Specify the IP address in dotted decimal format; for example, 127.0.0.1.
