javascript - Can we get the position of any device accurately with its IP address? If yes, which is the best API for that? -

-

how can position of device accurate city/street level, ip address. there api's powerful enough that?

i researched , found google's geolocation tools provide something—but not powerful , couldn't trusted 100%.

can find out position (with ip & other data fetch) on our own? there 'hybrid' apis combines different ip location finding tools(like google geolocation, ip2location or others) increase accuracy?

this question may not question, needed hints or links new apis/technologies. me.

note: answers specific 1 browser only, location welcome.

any appreciated. thanks.

i think it's not possible make work fine. example in poland in 1 of our mobile , phone operator (plus gsm) when use mobile internet show warsaw ip address.
