Possibly a new vector, I have IPv6 as well as IPv4 on a network. I see this segment of the (rather large) host file:
fa:16:3e:9d:de:21,host-192-168-2-103.openstacklocal,192.168.2.103 fa:16:3e:9d:de:21,host-2607-f088-0-2--1339.openstacklocal,2607:f088:0:2::1339 When I remove the second line, and kill -HUP the daemon, IPv4 starts working. I tried running kill -HUP without removing the line and did not get a response. Hopefully, whatever the problem is will be considered and fixed for both IPv4 and IPv6. I am running dnsmasq from ubuntu packages: 2.66-4ubuntu1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189909 Title: dhcp-agent does always provide IP address for instances with re-cycled IP addresses.
