# HOST-ADDRESS The HOST-ADDRESS command stores an IP address for the host and takes effect immediately. The IP broadcast address 255.255.255.255 can be used as if the host address is unknown or if you want several hosts to be able to receive DVL messages. A host port must be specified with the IP address. We use a default host port of 27000 because it is compatible with Blue ROV companion software. Examples: HOST-ADDRESS 192.168.2.2:27000 HOST-ADDRESS 255.255.255.255:27000 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
