Domain Name System (DNS) Services
Overview
Static DNS
You can use Static DNS to register a device with a free hostname in one of the
domains used with Dynamic DNS. Static DNS provides many of the same
services as Dynamic DNS, but it is tailored for devices whose IP addresses
rarely change. When you use Static DNS, new information takes longer to
propagate; however, DynDNS maintains a device’s hostname even when the
device does not send an update within 35 days.
Static DNS may be a good solution for you when:
■ your device’s IP address rarely changes
■ you want to assign the device a static, easy-to-remember hostname, but
you do not want to purchase a domain name
Custom DNS
You can use Custom DNS with both static and dynamic IP addresses. Custom
DNS provides all the features of Dynamic DNS, with several additions.
With Custom DNS, you can map a dynamic IP address to a hostname in nearly
any domain. (Exceptions include domains in alternate roots; see http://
www.dyndns.org/services/dns/custom/supported-domains.html for more
information.) You can also use your own domain, over which you have com-
plete control. You can purchase the domain name from another organization
or from DynDNS.
You can configure various hostnames in the domain. You can also specify
various subdomains, which can point to the same IP address or different IP
addresses.
You can configure Custom DNS using DynDNS’s standard or expert interface.
The standard interface automatically provides services such as having
www.yourdomain.com point to the same address as yourdomain.com.
