I’d been planning on finishing this project for a couple of months, but never really got round to it in till last weekend! The project is a web based prefix search which does a live search against the cty.dat file.
Seems to work well, not sure how useful it will actually be though but if you find it useful do enjoy using it and if you have any suggestions do let me know!
