This is similar to the ordering behavior of the legacy -gethostbyname function which is no longer used on most platforms. - -Addresses are not reshuffled if name resolution is completed using the DNS -cache. \fICURLOPT_DNS_CACHE_TIMEOUT(3)\fP can be used together with this -option to reduce DNS cache timeout or disable caching entirely if frequent -reshuffling is needed. - -Since the addresses returned are randomly reordered, the order is not in -accordance with RFC 3484 or any other deterministic order that may be -generated by the system's name resolution implementation. This may have -performance impacts and may cause IPv4 to be used before IPv6 or vice versa. -.SH DEFAULT -0 (disabled) -.SH PROTOCOLS -All -.SH EXAMPLE -.nf -CURL *curl = curl_easy_init(); -if(curl) { - curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); - curl_easy_setopt(curl, CURLOPT_DNS_SHUFFLE_ADDRESSES, 1L); - - curl_easy_perform(curl); - - /* always cleanup */ - curl_easy_cleanup(curl); -} -.fi -.SH AVAILABILITY -Added in 7.60.0 -.SH RETURN VALUE -CURLE_OK or an error such as CURLE_UNKNOWN_OPTION. -.SH "SEE ALSO" -.BR CURLOPT_DNS_CACHE_TIMEOUT (3), -.BR CURLOPT_IPRESOLVE (3) |
