    BT Infinity - Static IP

    I am looking at getting a wireless programmable thermostat for the house, and am consider a WI-FI connected one to control via my phone when I am likely to be delayed home from work - often.

    In order to do this I need a 'static IP' can anyone enlighten me what this is, and whether BT Infinity offer it? A quick google wasn't as clear cut as I would have liked!

    Cheers

    When you connect to the internet, your world-facing connection (i.e. your router, or a web server, or whatever) needs a uniquely identifiable presence. This is called an "IP Address". It is common for domestic ISP accounts to use what's called a "Dynamic IP", whereby you are allocated an IP address on a temporary basis when your router gets turned on, and might get a different one if you reboot it. More expensive connections (and business connections) have a static IP, where the IP address is guaranteed to persist across reboots.

    BT Infinity does NOT offer a static IP. Other fibre resellers may - or you can work around the issue with a DDNS service (e.g. noip.com) which is a personal domain name (andehh.noip.com or something) which is updated automatically to point to your dynamic IP, if it ever changes

    Re: BT Infinity - Static IP

    Thank you very much mate! Very clearly explained.

    The site you suggested seems to offer a static ip I can use for free, this seems to good to be true? Or is it like an AVG, where you get a basic (yet effective) service or payfor one with lots of other "nice to haves"?

    This is what you want I reckon. Good third party routers tend to have features built into them to help enable this to work effectively, not sure if the home hub does though?

    Noip doesn't offer an IP address, its a DNS entry linked to whatever IP you tell them, then you have software running to tell it what your IP is.

    Nifty as the doodad sounds seriously consider how long you'd need to have the heating off for to pay back the difference between that and the next one down.

    To extend on what Directhex has already told you - this is easy from the BT Homehub (it's actually a pretty good bit of kit).

    Settings -> Advanced -> Broadband -> Dynamic DNS.

    Turn it on, set it up with a provider.

    As bugger, and I swapped it out for a new one due to unreliable connection across the house! Will have to look into the new router (Belkin one) to see if it has a similar feature.

    So just to confirm, filling in the 'Dynamic DNS' details from the website (noip.com...) then taking the fixed IP said website gives me and giving that the thermostat would in theory do the trick?

    And it is £30 more for the Wi-Fi version. I figure that alone is worth the e-peen extending pub talk among my other home owners mates!

    I would assume that you would most likely also have to set port forwarding or a DMZ on the router for it to route it specifically to the thermostat's internal network IP.
