2.12.2 DHCP Connection
DDNS (Dynamic Domain Name System) provides another way of accessing GV-I/O Box
when using a dynamic IP from a DHCP server. DDNS assigns a domain name to GV-I/O Box
so that GV servers can always access GV-I/O Box by using the domain name.
To enable the DDNS function, first you should apply for a domain name from the DDNS
service provider’s website. There are 2 providers listed in GV-I/O Box:
GeoVision DDNS
Server and DynDNS.org . To register at GeoVision DDNS Server, see the following
instructions. For details on DynDNS, please consult them at www.dyndns.org.
