Re: [PLUG] Re: Just trying to ping my DSL modem

With DCAnet generally you need a MAC address per IP but I think you might
be able to netmask a block to a single MAC. I think you use to be able to
do that but something tells me thay may gave stopped doing that with new
customers. I suppose they do not like to do that unless you really plan to
use all of the addresses in the block. Otherwise they can assign single
unconsecutive address to MAC addresses. For the most part with port
forwarding you can live with one IP. I use to have a masked block of 8
with a former provider and thought I would not be able to live with just
one. So far it has been fine. The only program I have run into, that I
use, that requires an IP per instance is the amateur radio program
Echolink. I can only run one instance at a time on my network with one IP.
The nice thing about using the Linksys router as the front-end is that the
network does not depend on a running computer. I have a combination of
static and DHCP routing on the LAN side. I can come online with a computer
and it just works. This makes sense when you have many users, many of
which are windows. Why have all that stuff going thru a computer where if
something fails it brings the whole network down. You could also have
multiple routers (these things are only about $50 or less with rebates)
and multiple IP's and have multiple LAN networks. These could be tied
together on the LAN side allowing access at any point to multiple IP's
depending on which LAN you used - 192.168.0.x, 192.168.1.x etc...
