Re: IP Address Keeps Changing
Cable is an "always on" system. You use DHCP and your lease lasts X hours (usually 24 or 48 hours).
So if you go down for a few hours, your lease is still valid and when you get back up, your DHCP request just renews your current lease and you are given the same IP.
With Bell's inferior PPPoE, this is really a dialup situation The PPPoE is the equivalent of dialing the number to your ISP. PPP is then used to establish the session at the IP level, with authentication, and the ISP feeding you parameters such as IP address, DNS servers etc.
So, if your PPPoE session goes down for whatever reason, when you re-establish it, the ISP sees it as a totally new session and gives you new parameters.
If the previous session was not properly shutdown and you reconnect within 2 minutes, then the ISP will still have the old IP still allocated to your old session which hasn't timed out yet and will be forced to give you a new one.
If Bell based its offering on HSA, it would be like cable with an "always on" serice without that pesky PPPoE thing.
You might wish to call tech support whenever your session has been reset and ask them if they can look into the reason for your last session terminating, and if they can check lantern to see if your line sync was lost recently. |
