SENA Device Server and Serial_IP Application Guide - Manual (Page 11)

Note:
When using the Serial/IP in client mode, user application needs to know the IP of the Sena
Device Server. In this scenario, if the users network environment is DHCP, the IP address
might be changed whenever it reconnects to the network. Sena Device Server supports
Dynamic DNS Protocol that enables user to access the Sena Device Server via a domain
name.
