[Dnsmasq-discuss] Interface-name not injecting name into cache

[Eric Hiller]

I know this is a bit un-timely. But I wanted to reply so that this
information was publicly available.  For what seems an unknown reason to
me, the following will not work->

interface-name=wan,eth0
interface-name=lan,eth1

However this will->

interface-name=wan.domain.tld,eth0
interface-name=wan,eth0
interface-name=lan.domain.tld,eth1
interface-name=lan,eth1

As will this ->

interface-name=wan.domain.tld,eth0
interface-name=wan,eth0
interface-name=lan.domain.tld,eth1
interface-name=lan,eth1
interface-name=lan6,eth1/6
interface-name=lan4,eth1/4

So it appears you must at LEAST have the fqdn listed, then after that you
can have hostname-only as you please.

Hope that helps others.

Thanks
-Eric
