I'm using IP2Location’s free API plan. It's so good for me with 30K API Queries each month. It also provides what I need such as geolocation which I like most. Review collected by and hosted on G2.com.
The database pricing is quite expensive for me but it's not a problem because they also provided free database. However, it's seem that I can't import IPv6 to my database server because of very BigInt in CSV. It could be better if they use IP in fields instead of "Very Big Int".
