According to this post there are several ways to configure a custom host resolver in Java, but each of these ways differs from the other and does not work for all java versions between 8 and the most recent.
The post indicated above is 10 years old: does anyone know if in this period a solution has been found that works for all the java versions mentioned above? If so, does anyone have an example code?
After a deep search I found this example that uses the burningwave tools library:
Map<String, String> hostAliases = new LinkedHashMap<>();
hostAliases.put("my.hostname.one", "123.123.123.123");
HostResolutionRequestInterceptor.INSTANCE.install(
new MappedHostResolver(hostAliases),
DefaultHostResolver.INSTANCE
);
InetAddress inetAddress = InetAddress.getByName("my.hostname.one");
And here the code to add a DNS server connection based host resolver
