Hi, I had a look at [1] and AIUI this wasn't recognized as an upstream bug. I also can't find a relevant Debian bug about this issue. The bug description says it affected Xenial, which is now in Extended Security Maintenance, so it's a Won't Fix there.
For >= Bionic we need confirmation from an affected user the bug is still present and valid. Waiting for feedback I'm marking this bug report as Incomplete. [1] https://lists.thekelleys.org.uk/pipermail/dnsmasq- discuss/2016q4/011010.html ** Changed in: dnsmasq (Ubuntu) Status: New => Incomplete ** Changed in: dnsmasq (Ubuntu) Importance: High => Undecided -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1651044 Title: ProxyDHCP replies on invalid range Status in dnsmasq package in Ubuntu: Incomplete Bug description: In Ubuntu 16.04, I've configured dnsmasq to reply on subnet=10.160.37.0/24, yet it replies even when it gets an IP on subnet=10.161.254.0/24. I've only seen this after clean system restart. If I restart dnsmasq later on, it works as expected. Maybe when dnsmasq starts, the network isn't up yet, and it incorrectly initializes some networking information? I'm using network-manager with DHCP.
