Systems with dynamic IP addresses become accessible over the WAN - for example over the Internet - via so-called Dynamic DNS service providers, e.g. www.dynDNS.org.
Thereby a LANCOM becomes available under a certain DNS-resolvable name (FQDN -’fully qualified Domain Name’, for example "http://MyLANCOM.dynDNS.org").
The advantage is obvious: If you want to accomplish e.g. remote maintenance for a remote site without ISDN available (e.g. over WEBconfig/HTTPS), or to connect with the LANCOM VPN Client to a branch office with dynamic IP address, then you just need to know the appropriate Dynamic DNS name.
