The correct answer is: Four types

In Splunk, there are indeed four types of lookups defined. These lookups are categorized based on their functionality and the way they interact with event data. The main types of lookups are: 1. **CSV File Lookups:** This is the most common type, where Splunk uses a CSV file to map external data to the indexed data. These lookups can help in enriching event data with additional fields from the CSV. 2. **External Lookups:** These lookups allow the use of external scripts or commands to perform lookups against external data sources, providing greater flexibility for integrating and enriching data. 3. **Geo Lookups:** Designed specifically to convert IP addresses into geographic locations, geo lookups are crucial for geographic analysis in Splunk, allowing for better visualization and reporting. 4. **DNS Lookups:** This type allows Splunk to resolve hostnames or domain names to IP addresses and vice versa, which can be beneficial for incident investigations and monitoring network activity. Understanding these types of lookups enables the Splunk administrator to effectively utilize external data to enhance analysis and reporting capabilities within the platform. Each type serves a unique purpose and can significantly improve the context and understanding of the data being analyzed.
