# Hello autumn, hello Palladian 2.3! 🍁

Palladian 2.3 contains three new “GeoIP2” nodes for resolving Geo-related data based on IP addresses via [MaxMind](https://www.maxmind.com/). This is perfect for analyzing log data, getting statistics about your web site users, or detecting fraud behavior.

> **[GeoIP2 Extractor — NodePit](https://nodepit.com/node/ws.palladian.nodes.maxmind.geoip2.extractor.GeoIP2ExtractorNodeFactory)**
>
> Allows to extract location-related data for IP
> addresses via MaxMind.

> **[GeoIP2 WS Connector — NodePit](https://nodepit.com/node/ws.palladian.nodes.maxmind.geoip2.connector.ws.GeoIP2WSConnectorNodeFactory)**
>
> Connect to MaxMind’s Web Services.

> **[GeoIP2 DB Connector — NodePit](https://nodepit.com/node/ws.palladian.nodes.maxmind.geoip2.connector.db.GeoIP2DBConnectorNodeFactory)**
