Hi Thomas -  I'm sorry for the really long delay in replying.  For some reason,  I missed this email when it arrived, and only now found it when I was glancing through the other emails.  Of course, I was glad to hear that the option would be added to dhclient - it would save me patching it for each update, and would definitely be useful to others as well. If possible, and if it's not too late, I would like to be mentioned as Indy, of the FireballISO open source project (https://fireballiso.sourceforge.io/). It's up to you whether to put in the URL. Thank you! -Indy On 11/27/2017 9:03 AM, Thomas Markwalder via RT wrote: > Hello Indy: > > You'll be pleased to learn that we have added a command line argument, --prefix-len-hint, to dhclient that instructs the client to use the specified value as the prefix length hint when soliciting prefixes.
