dhcpcd-discuss

One more update and then I'll shut up and wait for some input. :-)

I thought maybe the interface was using stateless configuration, and that's
why `--dumplease` had no address, so I tried the "ia_na" option. I get an
IPv6 address and can ping, but the lease dump got worse and now has an
error in it:

$ sudo dhcpcd --dumplease eth2
broadcast_address='172.20.10.15'
dhcp_lease_time='85536'
dhcp_message_type='5'
dhcp_server_identifier='172.20.10.1'
domain_name_servers='172.20.10.1'
ip_address='172.20.10.6'
network_number='172.20.10.0'
routers='172.20.10.1'
server_name='[censored]'
subnet_cidr='28'
subnet_mask='255.255.255.240'
eth2: dhcp6_dump: No such file or directory
