Hello
Maddy123,
With the question posed, it leaves me a little worried that no-one planned the creation of the servers very well. Are the people asking this wanting to:-
- add the details to the /etc/hosts file on the server in question?
- add the details to the /etc/hosts file on all the unix servers? (and equivalent on windows servers)
- add the details to a DNS server?
I'm concerned that the planning should have been done in advance for something as fundamental as server name and IP address resolution. How did you get to where you are? Were these toy servers built by application developers who now want them put to a production use?
The preference for converting 'server name --> IP address' and 'IP address --> server name' would be with a DNS server (or a few for resilience) That way, one update is reflected to all servers so if things change you don't have the risks associated with multiple updates being required, i.e. errors, forgotten servers, sequence of update, which process has last save etc.
Perhaps with a little more context, we can help you more than you are asking.

NAME
CURLOPT_DNS_SERVERS - set preferred DNS servers
SYNOPSIS
#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:
192.168.1.100,192.168.1.101,3.4.5.6
The application does not have to keep the string around after setting this option.
DEFAULT

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.
