Domain Name System (DNS) Services
Configuring Dynamic DNS
Configuring Dynamic DNS
When an interface has a dynamic IP address—for example, when your ISP
provides its address—you should register its hostname with a dynamic DNS
service provider. Dynamic DNS keeps track of the static hostname and ensures
that, even when the associated device’s IP address changes, the hostname
resolves to the correct address.
The ProCurve Secure Router supports a client that is compatible with
Dynamic Networking Services, Inc., or DynDNS.
The dynamic DNS client on the ProCurve Secure Router can request one of
these three levels of service:
■ Dynamic DNS
SM
■ Static DNS
SM
■ Custom DNS
SM
Dynamic DNS and Static DNS are currently free services. Dynamic DNS allows
you to map a dynamic address to a static hostname in one of 68 domains. Static
DNS provides much the same services, but for devices whose IP addresses
rarely change. DynDNS provides both these services for up to five hostnames.
You can purchase Custom DNS for a complete DNS solution. Custom DNS
grants you control over an entire domain name: either one that you purchase
from DynDNS or one that you have already purchased from another organi-
zation. You can also configure subdomains and map them to the same IP
address or different IP addresses.
You should visit www.dyndns.org for more information about these services.
The following router interfaces can register for dynamic DNS services:
■ Ethernet interfaces
■ Ethernet subinterfaces (VLAN interfaces)
■ Point-to-Point Protocol (PPP) interfaces
■ High-level Data Link Control (HDLC) interfaces
■ Frame Relay subinterfaces
■ Asynchronous Transfer Mode (ATM) subinterfaces
