This is a client for dynamic DNS services, aimed at ESP (ESP32, etc) devices. Your node can use such a service to make its IP address known as a public DNS name, so you can find it, and use it from applications.

Dynamic DNS client library for ESP32
Copyright © 2019, 2020, 2021, 2023 by Danny Backx
The supporting functions for DynDNS allow you to have active FQDN, even on more than one name for a single device :
dyndns = new Dyndns(config->dyndns_provider());
dyndns->setHostname(config->dyndns_url());
dyndns->setAuth(config->dyndns_auth());
dyndns2 = new Dyndns(DD_CLOUDNS);
dyndns2->setHostname(DYNDNS2_URL);
dyndns2->setAuth(DYNDNS2_AUTH);
and then run code like this periodically both on dyndns and dyndns2 :
if (dyndns && (nowts > 1000000L)) {
if ((dyndns_timeout == 0) || (nowts > dyndns_timeout)) {
if (dyndns->update()) {
ESP_LOGI(app_tag, "DynDNS update succeeded");
// On success, repeat after a day
dyndns_timeout = nowts + 86400;
} else {
ESP_LOGE(app_tag, "DynDNS update failed");
// On failure, retry after a minute
dyndns_timeout = nowts + 65;
}
}
}
