+# NAME
+
+CURLOPT_IPRESOLVE - IP protocol version to use
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IPRESOLVE, long resolve);
+~~~
+
+# DESCRIPTION
+
+Allows an application to select what kind of IP addresses to use when
+establishing a connection or choosing one from the connection pool. This is
+interesting when using hostnames that resolve to more than one IP family.
+
+If the URL provided for a transfer contains a numerical IP version as a host
+name, this option does not override or prohibit libcurl from using that IP
+version.
+
+Available values for this option are:
+
+## CURL_IPRESOLVE_WHATEVER
+
+Default, can use addresses of all IP versions that your system allows.
+
+## CURL_IPRESOLVE_V4
+
+Uses only IPv4 addresses.
+
+## CURL_IPRESOLVE_V6
+
+Uses only IPv6 addresses.
+
+# DEFAULT
+
+CURL_IPRESOLVE_WHATEVER
+
+# PROTOCOLS
