[Dnsmasq-discuss] dnsmasq, give IP address a name

[T o n g]

Hi, 

How can I give an IP address a name? 

We can use 'address=' to map name to IP, and 'alias=' to map IP to IP, 
but how to map IP to name? 

The reason that I need this is that, I'm adding a second IP address to my 
DNSmasq server using a virtual interface, see,

but now I need to give such second IP address a name. How to do that? 

Thanks
