Only issue you will have is if the DNS dies and you loose logging from all 5k servers. That would suck...

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_SERVERS, char *servers);
DESCRIPTION
Pass a char * that is the list of DNS servers to be used instead of the system default. The format of the dns servers option is:
host[:port][,host[:port]]...
For example:

AVAILABILITY
This option requires that libcurl was built with a resolver backend that supports this operation. The c-ares backend is the only such one.
Added in 7.24.0
RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, CURLE_NOT_BUILT_IN if support was disabled at compile-time,
CURLE_BAD_FUNCTION_ARGUMENT when given an invalid server list, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
