But Jason in a former psot said that no matter if the lease tiem renewal comes i will still have the same ip address otherwise the current communication i may be having at the moment would be disrupted.
So from that he clearly states at "If you have a dynamic IP, the automated system will TRY to give you the same IP each time your lease is renewed. Again, the ISP has your MAC address on record, and it will try to give you the same IP you had before the lease expiration, as long as somebody ELSE didn't claim that IP first. "
Claim it when? The time i was already using it? Even if he did, the server woudl deny it, and even if the lease renewal tiem comes upa gain it will take a sec before it get renewd to the same again. So there is no time for someone ELSE to take the ip address.
You have static ip = no dhcp/ manual assignment/ infinite lease time You have dynamic ip = dhcp assigned/automatic assignrmnet/has lease time You have static ip assigned by dhcp = ip reservations/no lease time == mappign the mac to the specific ip address.
My isp very well may be doing the ip reservations for the wan interface of my router/modem which is why iam always getting the same ip address.
But lets see examine all 3 cases:
1st case iam not for sure because i have a contract for dynamic ip addressing not static otherwise i would pay more and in 6 months now my ip address changed one time. So its not number one. Also the isp coulnst manully configure my modem/router :-) which can happen though by distance on case 3.
So thats leaves us 2 and 3 cass. Which one?
I thought i was number 2 but wouldnt my ip change every time i connect or so as it does with other friends of mine that also have dynamic ip addressing? But in their case they have an adsl modem not an adsl modem/router, maybe that matter too.
In case 3 of mapping(which i tend to beleive i have cause my ip changes every 3 months or so) wouldnt that fal to case 1 again which is static with the difference that it wont have a lease time?!? But then again i didtn pay for a static one although i like it!
ok i start to sound crazy again! Like iam on a labyrinth or something :-)
Also tell me a case that i could lose my dynamic ip address i usuallly have 3 months now in my case 18.104.22.168.
3 m "Without a lease I can't see how it would be possible to be sure that a client has "been retired" (Doesn't need an IP because it no longer exists). "
Cliant has been retired = client either switced off his comp or disconnected from the network?
In those cases the server waits the lease time to check and free the "retired" ip address back to the ip pool or gets nottified immediately?
