The Ipregistry batch endpoint allows grouping multiple IP address search requests into a single one. This really speeds up the processing when you have a bulk of IP searches to perform.

The batch endpoint was accepting up to 256 IP addresses per request until recently. Starting today, we’ve increased this limit to 1024.

To give you an idea about how fast and powerful our API is, let’s assume you are sending requests in parallel using 8 threads from a node that has about 40ms latency to our API, then you can resolve 600,000 IP lookups in one minute or less.
