[Dnsmasq-discuss] ignoring unknown MACs

[Sameer Verma]

I found this post:
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2009q3/003258.html
which indicates a problem with dhcp-ignore=#known and a fix in
2.51test3 (and presumably beyond). Can anyone verify if this is the
case? I am using 2.50 with Ubuntu Karmic.
