Cable net + Switch/router?

Ok, this is confusing the heck out of me now, I know basically nothing about routers/switches etc.

A friend of mine will soon be getting cable internet, he will be getting a modem from his ISP, which will have an ethernet connection coming from it...
The net will need to be shared with 4 or possibly more machines, now he's after a router, but I suggested a switch (as they're more efficient, right?) but he says he's not sure that will work, what I want to know is can the modem be connected directly to a switch, which will distribute the net across the network?

a switch will require him to purchase multiple IP addresses from his ISP. A router will use one IP address and through it's built in DHCP server and NAT translation it will assign local addresses. It will use the router for DNS and a gateway. A router also makes for a nice hardware firewall. I suggest the router.

Edit: A router IS a switch, it just has one port on it that sits on the internet end of the network and 4+ that sit on a more secure closed network...

Edit again: There are a FEW... an very few... cable modems that have builtin DHCP servers that would allow for you to use multiple PCs without purchasing additional IPs. In this case you could use a switch. I still recommend the router however because it gives you total control over your network. It gives you the ability, through NAT translation, to host WWW, FTP, and other services on different PCs and still use a single IP address. Most of them have parental control built into them where if you try to access a webpage with words you enter into the parental control, it will deny it. NAT firewalls work well but SPI (Stateful Packet Inspection) is much more secure even than NAT. Together they do a really good job. I will see if I can find some more information on a webpage for you...

Thanks for that, cleared a few things up in my head :)
I'm pretty sure that he's stuck with just the one IP (guess I'm lucky, my ISP gave me 5 even tho I only have one machine :confused: :D )

^^^^^ What he said^^^^^
Yup, Un4givEn1's right SPeedY.
Aim for a router with built in Firewall if possible. Extra layer of security, plus port stealthing :D

I have the ability to purchase a "pro" service from my ISP, where they would give me 5 as well. The pro service also doubles the download speed and triples the upload speed.

What type of connection do you have SPeedY_B?
First I've heard of an ISP giving 5 IPs to a customer. haha

My IP is dynamic even though I have a cable modem (ntl)
Interesting to hear of "5" addresses gratis. ;)
Would be nice, although redundant if connecting all PC's through 1 router.

for how much more $$?

yep... US

It's $79 a month for that service...

I still miss day days back when cable was new... I used to get killer speeds because none of the companies had bothered to cap them. I remember pulling 15MB files in 4-5 seconds. That rocked! True upload speeds of 400-600Kps! I miss those days.

SPeedY, Henyman, and myself are stuck with the broadband retarded UK ISP's lol

lol :cool: Very true. I've been with cable since moving of 56K and every contact with ADSL has been, in comparison, very poor.

Pipex is under that very poor catagory.

From what i can tell Griffin rocks the ADSL world :)

I'm on a 512/256 ADSL line, and my ISP is Griffin, using their Copperstream 500 home package (£19.99/mo with vat comes to about £23.50)
Nice! Better than Pipex for a package that costs the same.
I'm interested in the Bulldog service at the moment, but not willing to spend anything more than what I'm spending now.
Bulldog offering 2mbps during offpeak hours for £29.99.

As far as I know, Pipex is actually better than most other DSL providers. :)
