will a switch work for this

[alchemist]

In my future appartment, I have a single RJ45 connection comming in from the building's router. I am not given a permanent IP I've read the FAQ but i dont know it is the same in this case since my ip isnt permanent. Can i connect this to a switch and then simply connect my other computers to it to get internet access since I am assuming that each computer attatched will automatically be given a different IP since its not assigned the same IP all the time?

my assumption is that your apartment will be given 1 ip. i doubt that you will be assigned multiple IPs because your apartment is only given one branch of the building's router. correct me if i'm wrong, but i would think that you would need a router, not switch. that way you could connect multiple computers and use the single ip that is assigned to your apartment

Talk to the apartment management (or whoever manages the network) and ask how their address pool works. You could get multiple IPs through the one jack...that's no biggie at all, and the switch would work fine....if that's allowed.

It's more a matter of policy than technology. If they only grant you one IP address, to use more than one computer, you'd need a router that does NAT, or another machine doing ICS or acting as a router (that does NAT). If they'll give you up to five IP addresses, and you don't figure you'll need more than five, then a Switch by itself will be jus' fine. If they'll grant you five, and only five, and you think you'll probably have more computers than that, then you should probably get a couple addresses, and still use the router.

Good Luck

They told me that i could get by with a hub and dont need anything to do NAT, so I assume that means that each of my computers would be randomly assigned a different IP. Therefore a switch would work since each computer has a diff IP?

You are correct sir.

alchemist,

ScottMac is right that it would be a matter of policy, rather then technology. But, I can't help but think that it is unlikely that they are dishing out multiple IP addresses to each apartment.

For one thing, how would they know how many addresses to allocate to each unit? How many to lease in aggregate? If they were passing out as many as the renter wanted, people (like me) would be in there running a couple dozen nodes.

Address space costs money, and the rental market is competitive and subject to price sensitivity and competition. Unless you're in some fancy-schmancy neighborhood, I can't see them leasing more then one per unit with a handful of spares.

Wow! haven't done that in a while. I posted one reply over another.

The addresses that the apartment complex is handing out are probably private,
which would not increase costs. Then the complex NAT's to one address, just like
our building net.

With private addressing, no one apartment probably will have enough machines
to matter. Even ScottMac only has about a half dozen in his house. 🙂
