Maxmind has a free and pay for use version of their service. It's excellent, has a Pear class you can use Net::Geo_IP (IIRC). Just install whatever version of their DB you need and you're all set. Have used it many times.
Try Geonames: you can download their database and then maybe index it with Solr or something to give you a service isolated from the outside world and which you can update on a needs basis.

尝试 Geonames：您可以下载他们的数据库，然后可能使用 Solr 或其他东西对其进行索引，以便为您提供与外界隔离的服务，并且您可以根据需要进行更新。
