Which particular ISP in Canada offers multiple dynamic IPs?

Out of curiosity - I was wondering if there are any ISPs in Canada that offer multiple dynamic (DHCP) IP addresses.

I remember one time that Shaw offered that instance - 10 years ago. Not sure if they are still doing it. I know Rogers doesn't do that - unless you request to add one to your account.

If my memory serves me right (and this was 10 years ago), I once tried to connect two computers to the internet - using a simple hub. While I was able to share files and folders between these computers in a "wired" fashion, I was "powerless" on completing this objective. As it turns out, I bought a wired router and all is hunky dory.

I have since gone wireless and times do have changed. Anyways, does anyone know which particular ISP in Canada offers multiple dynamic IP addresses?

Nobody offers multiple dynamic IPs (which is technologically difficult if not impossible), but many ISPs offer multiple static IPs, which will serve you just as well, since there are no legitimate advantages to dynamic IPs.

I was under the impression that one could acquire a static IP just by changing the router settings. Are there companies that don't allow that (or even port forwarding)?

Oh? That's news to me.

I would prefer dynamic instead of continually being tracked by one set of numbers.

So I wouldn't say there is no advantage to it. But rather, to you, in your use and your opinion, and to your understanding, you find no need for dynamic. Other still do prefer it.

static IP has nothing to do with the router in your home. It's all setup on the ISP side.

Rogers used to do it for $9.99 additional per month. Not sure if they're still able to do it. Then you'd just put a switch behind the modem.

Not sure why it would be difficult, as Guspaz says (genuinely curious, could you elaborate on that?).

I am not sure I understand your question, but when it comes to DSL, it is trivial to obtain multiple dynamic IP's (although, depending on the ISP, they may or may not like you doing it).
E.g., if you setup a DSL modem in a bridge mode and connect two routers to it, each router will be able to establish a PPPoE session and acquire a different dynamic IP.

Go with DSL that uses PPPoE. Each time the modem re-connects you get a new IP. I generally had a new IP each day when I was on DSL. With cable I go around 4-8 months with the same IP before it changes.

Many of them offer this.

Bell DSL & wholesale allow you multiple concurrent PPPoE sessions, unofficially.You can connect to your DSL modem via switch/hub and get multiple dynamic ip addresses.

you could do for instance connect 3 different routers to a switch which is connected to a dsl modem,

each would have their own dynamic IP, established by PPPoE.

I believe telus allows you to do the same thing (or at least they did), except they use DHCP and restrict you to 2 IPs maximum.

As for multiple 'dynamic' IPs assigned as a block to 1 router, I don't think that exists.

Bell's new official policy (as of this month) is to ban customers who connect more than a single simultaneous PPPoE session.

Getting multiple dynamic IPs through multiple PPPoE sessions is easy (but not really allowed), but it's not a correct solution. Getting multiple dynamic IPs through a single PPPoE session, that's hard.

The difficulty comes from the fact that while an ISP can route multiple IPs to a PPPoE endpoint (your router), the protocol, as far as I know, only has provisions to inform you of one of those IPs. So they'd have no way to tell you what IPs that were allocated to you. It works with multiple static IPs because your ISP told you in advance what they would be.

For cable, upon further thought, it wouldn't be so hard, I guess they'd just have to remove the MAC-locking that prevents more than one machine from making a DHCP request to the modem. But then you'd have no router to manage traffic, leading to local congestion scenarios, which isn't ideal.

In fact cable often allows 2 IPs now. Not official, like the multiple PPPoE session thing, but you can sometimes do it.

I recall years ago like in 98 i paid $5 bucks extra a month to rogers for a second ip on my cable modem.

wow, way to drop a bombshell on us ...

Anyway who your source is, but I can tell you there are tens of thousands of customers on 2wire or similar hardware that connect twice because they are using their own router and haven't bothered to remove their login details from inside the 2wire..

Stands to wonder they'd suddenly want to crack down on this after allowing fifteen simultaneous PPPoE sessions per line for years and years...

Well, Bell scared wholesalers into similar limitations years ago... You'll notice that nobody sells secondary logins anymore?

I know for sure that Cogeco used to offer 2 or 3 IPs on all but their lite package. It used to say that on their site too. Here's a thread from 2003 talking about using multiple IPs on Cogeco.

But now that all their packages have changed, I don't know if that's the case, and their website is silent on the issue.

So the only way to know is to try it out. Hook up a switch to the modem and plug two computers into the switch. If both computers get Internet IPs, then you're golden!

Which particular cable should I use for linking my two computers and the modem? Straight through or Crossover?

Yes, why would they want to prevent users from abusing their service and using up IP addresses that could go to legit customers instead of customers doing stupid things with their service.

As if its such a surprise that companies do go back and review policies or configuration decisions from the past.

As if having a dynamic address makes it anymore difficult to track you.

Straight through if you're going into a switch.

If I remember correctly, you only use a crossover if you're going from one computer directly into another - although, I think newer network cards are smart enough to use a straight-through for that too since it's worked for me before.

Unless you're using old equipment it does not matter if you use a crossover cable or not. Anything with a GigE port and the vast majority of equipment nowadays with a FastE port uses PHY which supports Auto MDI/MDIX which removes the necessity to use a crossover cable when interconnecting host to host or switch to switch. Only one end of the link requires this. As in if you have a reasonably new enough switch you don't have to worry about whether the devices connected to it support Auto MDI/MDIX or not.
