Hi Daniel,
Thanks for the response!! I was using v1.25 and the patch has been
integrated in v1.31 and I will update to a newer version. As mentioned
in the patch, the same block will be only offered if it was not
allocated for any other device. Should we think of a way where we
maintain the offered blocks for a particular device so that next time
the same is offered or more freedom to the application in choosing its
subnet?
Best Regards,
Usman

This should be addressed by 09963fa93f0b ("ippool: Try to assign the
same subnet while tethering"). Which version of ConnMan are you using?
cheers,

Along with getting more stable IP blocks you get a bunch of bug fixes as
well (and hopefully no regressions :)).
As mentioned
in the patch, the same block will be only offered if it was not
allocated for any other device. Should we think of a way where we
maintain the offered blocks for a particular device so that next time
the same is offered or more freedom to the application in choosing its
subnet?
Of course we could implement something like this but I would like to
know why is that so important? Is it because you have static IP
addresses assigned to devices which use the uplink?

And let's not forget that sooner or later an uplink service will end up
issuing an IP on a subnet that clashes with a pre-defined tethering
subnet. These cases are now detected, and tethering restarted with a
different subnet in order to provide Internet connectivity as the
primary target for ConnMan. Finding the hosts on the tethered subnet
has been left as an excersise for mDNS.
