* rewrite the hole script:

Browse source 
** use .env file for config so we can retrieve updates
** add config and payload DTO with validators
** allow registrable domains as DynDNS
** update IPv4/6 only if changed (or really forced)
** remove obsolete failed_logins counter
** save logs with timestamp
** save only the newest 100 log entries for each domain
