How long has it been since your IP address changed?

[nstgc]

I was curious about this so I sifted through my posts. It seems as if the last time my IP address changed was some time in May 2008, despite attempts to get it changed.

[Tiffanys]

Hell if I know.

[megido-rev.M]

Ever since I changed the connection type.

At least since 2012 April. My log does not go further than that. No more than 3 years though, back then I had DSL and my IP changed all the time.

Dynamic IP, changes all the time.

I am supposed to have a permanent IP so the answer should have been 4-5 years since that where when I moved in here. But about a year ago there where some network problems, the town changed company to do network maintenance and it turned out that the old company had kept no documentation at all. Took them about 2 months to get everything sorted and during that time the network where very unstable and my IP changed randomly.

Was a major headache for me because I run the server with all anime for our club. Coming to the club and try to download something to watch only to discover that the IP has changed during the time it took to walk from home to the club... Sure there workarounds but still a major headache.

Since whenever I last rebooted my router. Which, considering how many problems it's causing atm, is probably no longer than a day.

Mine last changed sometime in October or November. I remember it pretty distinctly because I had to go and change my dyndns name manually to get something back up right away.

I've had the same IP ever since I moved a couple of years ago, even though I'm supposed to have a dynamic address.
Edit: I use dyndns either way in case it ever changes.

I'm suppose to have a dynamic IP as well, but I don't apparently.

I'm suppose to have a dynamic IP as well, but I don't apparently.

I like having a static IP - when I had dynamic IP I had to use a program that would monitor the IP and restarted all torrents if it changed (to update trackers about my new IP). I no longer need to do that.

ISPs like to specify dynamic IP for home connections so they can get away with changing the IP if they need to (unlike business class connections where the IP is usually set in the router and not assigned by DHCP). This also forces people who want a real static IP to pay more for the business class connection.

I technically have "Two" IP addresses because my Internet goes through a little equipment called the Motorola Canopy. The Internal IP starts in the 192.168.x.x range and the External IP (which is static) is where the Canopy connects to the Basestation.

The reason I don't like it is that the sites I got to have something else they can use to track me. Its a privacy thing. It doesn't help if you are doing something criminal since my ISP would just hand over the data, but for other places they can more accurately put together a picture of who I am, which is disconcerting.

I find that more often, at least in the UK, when they specify dynamic IP, they generally just mean that you're assigned to whatever IP happens to be available in the pool when you (ie. your router) connects. Since ideally you don't ever need to reboot your router for months, or even years if you're lucky, you just end up with the same address for that entire period.

That's how DHCP works. But some ISPs (like mine) have a database of the assigned IP:MAC mappings, so even if I reboot the router, I still get the same IP (which is good for me), but if I connected another device (or changed the MAC of my router) I would get a new IP.

They can do it with other methods more accurately than using the IP (which could have 10 PCs behind it). Well, if you don't want to be tracked at all, there's TOR, VPNs and similar services.

Well, DHCP leases expire after a certain period of time (usually a few days in the case of ISP-assigned IP addresses) and need to be renewed; a truly dynamic IP address would change each time this occurs, since you are just assigned a new one, rather than being reassigned the one you used previously.

But you're right of course, different ISPs do things differently. I was just mentioning what's most common here in the UK.

There is no point in forcefully changing the users IP, especially since it would cause a momentary interruption in services (all connections made with the old IP would be broken, hope you weren't playing online or uplaoding a large file to a server that does not support resume).

When the lease is expiring, the client essentially asks the server "Hey, I'm still using this IP, can I keep it?" and usually the server allows it to keep the IP (because as I said, changing the IP would break established connections). If the ISP provides dynamic IP, the IP usually changes when the client is restarted (and then asks the server for any IP), if the DHCP server does not have a database, it will most likely give out a new IP.

OTOH, the DHCP server in Windows 2003 will give out the same IP as long as the lease is not expired. Though I have not tried releasing (ipconfig /release) and then renewing (ipconfig /renew) the IP, maybe it does change then.

And some ISPs I know use quite short leases (something like 30min or 1h), the downside of that is that if the DHCP server goes down the clients soon lose their IPs (and the connection).

That's interesting. I've personally found that my IP doesn't change as long as my router and modem stay up, even if everything connected to it shuts down, and as long as I don't manually renew it. I didn't know there were people whose IP addresses change every day on their own.

[JoonasTo]

Everytime I restart my computer since bridged dynamic.

I did have static IP for a year until the guys at the tel noticed it. Nifty for remote control.

Like the situation at my end. I theoretically can change the IP, but it won't regularly by itself especially if the modem never reboots.
