On the back of my router-box there is a domain-name of a web-site. This domain-name/web-site is the one of the vendor of my router. There are also a credentials - user-name and password - to enter/log-in into the admin-panel of my router.
for Netgear router http://www.routerlogin.net user-name: admin-password: password
In which cases should one make use of this way to remote log-in to the router besides that there is already another method for remote router-log-in - by enabling remote access on the router locally and creating ddns in advance?
