I thought Telecom operated dynamic IPs for residential customers. The IP would likely not change often if you remain connected to their network but a static IP is not guaranteed.

For the last 6 months I have been randomly checking my ip number. So far it has stayed the same. I have a feeling it has been the same for longer than that, but only a feeling. I'm on Slingshot.

If you are on the newer Telecom UBA-based broadband connections you might find that your IP doesn't change very often (usually only if you move houses or change DSL ports at the exchange/cabinet).

If you're on the older FIPD broadband connection, you'll get a new IP everytime you connect (unless you have a static IP).

Slingshots dhcp server has a long timeout value set for something like 18 hours. If a modem goes offline, it is held for 18 or so hours before it goes back into the pool, so it may feel like you have a static ip but your modem hasn't been off for long enough.
This is a well known quirk of slingshot but something they don't publicise.

Many ISP's are also using sticky IP's these days as it makes compliance with s92 a lot easier.

You could have just been migrated off the old FIPD onto BBA. Which is happening in the background or if you ring up Telecom and move to a newer Total Home Broadband plan and you were on an older plan.

Normally if you're on BBA your IP address doesn't tend to change. Unless you specifically requested a Static IP address however it can change a no notice.

@l43a2: More than likely we've just moved you around on our network.

When we do this, your IP address (if it is not a static IP) will very likely change. If you do want to have an IP address than NEVER changes, then suggest you order a static IP.

Many of the plans come with a static IP for free, but you don't automatically get one - you have to ask, otherwise you'll get one that could be the same for long lengths of time, but could change without notice at any time.

My views are my own, and may not necessarily represent those of my employer.
