      This class is responsible for mapping DNS names to [IP:Port]. Internally, it caches DNS responses as long as their TTL is valid to avoid unnecessary requests to DNS servers. Initial version only needs to handle resolving DNS_NAME -> single A record or DNS_NAME -> CNAME record -> single A record.

      class LDAPResolvedHost {
private:
    SockAddr _address;
    std::string _hostName;
    bool _isSSL;
}

class LDAPDNSResolverCache {
public:
    // Does a DNS resolution to resole LDAPHost to one or more LDAPResolvedHost
    // Caches DNS responses until TTL. If entry is expired, resends lookup first
    std::vector<LDAPResolvedHost> resolve(const LDAPHost& host)
};
