Hello, Does ConnMan support any type of IPv4 address conflict detection? I searched the code, but wasn't able to find anything obvious. I need this functionality for DHCP and manual configuration methods. RFC5227 (https://tools.ietf.org/html/rfc5227) describes a sequence where a client should probe an address with ARP, and not use the address if it's already in use on the network. Apparently udhcpc (https://busybox.net/downloads/BusyBox.html) supports this functionality through its command line option --arping. Thanks, Dave Berg
