A new firmware update for the Lumia 625, Lumia 925 and Lumia 525 started to roll out just over a week ago for a few users and with it came a small, but useful feature: static IP. The ability to set one's particular internet gateway and IP details is something nuanced, but essential for some users on various networks. Windows Phone's ability to support static IPs is as far as we know dependent upon the phone manufacturer as the OS itself does not have this baked in.

The firmware itself is slight, coming in at just 18 MB. It bumps the revision number from 1425.0002 to 1425.0003 on most devices, bringing the new static IP option, network+ option and some bug fixes, according to reader of the site Vinod K.

So far, it seems only phones with the Lumia Cyan update and Windows Phone 8.1 are getting this new firmware, and it is limited to select Lumia 525s, Lumia 625s, and Lumia 925s including those in India with carrier Aircel. Last week, we had numerous tips from users about such a firmware update, but in lacking specifics i.e. what changed, there was just not much to report on until recently.

Presumably, other Lumias may get this update too, although it is not clear if the new features extend to the full range of Lumias or is just limited to those in emerging markets.

Is the ability to set a static IP a feature you would use on a Windows Phone?
