# FALLBACK-ADDRESS The FALLBACK-ADDRESS command stores a static IP address for the DVL for use during the next boot-up and is only used if there is no static IP address set and DHCP fails. Setting an address of 0.0.0.0 or 255.255.255.255 as a fallback address is not allowed. The DVL ships from the factory with the fallback address set to 192.168.2.8. Example: FALLBACK-ADDRESS 192.168.2.8 --- # 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.
