[AccessD] OT: Wireless network (sort of)

GREAT policy!  It should get more of this list signed up for the other lists
especially the tech list.

Good job moderators!

Nicely put. However <bzzzzz!> by being the first person to post to this
thread today, you fall foul of a new policy just agreed between myself and
the other moderators. Don't take it personally...

EVERYONE PLEASE NOTE: from now on we will be insisting that responses to
questions which really belong on one of the other lists MUST be made on the
appropriate list and not on AccessD.

Initial requests for help can still be sent to AccessD, until it becomes
clear that we have enough subscribers on the other lists to make it
unneccessary, but all responses should be sent to the VB, SQL-Server or Tech
list.

We will be sending out an official email to that effect sometime soon.

If you disagree with the policy please send a mail to
ops-mod at databaseadvisors.com and we will consider your views.

Thanks

Roz

Think of a subnet as a neighborhood.  A network neighborhood.  The subnet
'mask' is a property in TCP/IP, which tells your machine what IP addresses
are around it.  It's a bitmask thing.

192.168.0.1, with a subnet mask of 255.255.255.0 tells the machine that
192.168.0.1 through 192.168.0.255 are around it.  If the bit is turned on in
the subnet mask, IP Addresses in that subnet must have a matching bit
(either on or off....), if it's turned off in the subnet, that bit in the IP
address can be different.  So 255.255.255.254 for a subnet, is a subnet of 2
machines.

The reason this is important, is because subnets control how much
broadcasting and browsing your machine must do, to locate other computers on
the network.  A subnet of 255.255.0.0 tells your computer there are 65k
machines on the subnet, and more then likely you will never find anything,
because it will eventually give up.  255.255.255.0 tells it there are 256
(255) computers on the subnet, which it should be able to find just fine.
However, if you have a smaller network, a smaller subnet speeds up the
'searching'.

That leads to what I was talking about earlier...the Gateway (router).  When
you tell a machine to go to 123.456.789.321, if that IP Address is not on
the subnet, it doesn't even bother looking, it just sends the request to the
gateway IP (router), so the router does the searching.

O. What's a subnet?  And where do I get one?  And do I want one?
