Static IP Service (cont.)
Reverse DNS (Domain Name System)
Reverse DNS is the practice of mapping an IP address to a host name. This is usually needed if you plan to
host a mail server. Our technical support team will validate and publish Reverse DNS in response to your
request. To access this area:
1. Go to optimum.net.
2. Sign in and select the
"Optimum Extras" icon.
3. Select "Manage IP Configuration"
and follow the instructions provided.
Important: Please note that our ability to
publish Reverse DNS is dependent upon
timely DNS changes to the Host Name
record. At least one of your forward entries
must match the requested reverse entry
within 72 hours or the Reverse DNS
submission will fail. Once the Reverse
DNS is validated, it will take up to 6 hours
for your pointer record to propagate
the Internet.
Dynamic DNS (DDNS - Dynamic
Domain Name System) Features
DDNS allows an Internet domain name to be
assigned to a computer with a varying
(dynamic) IP address. This makes it possible
for other sites on the Internet to establish
connections to the server without needing
to track the IP address themselves. If you
wish to access the Dynamic DNS
administrative area:
1. Go to optimum.net.
2. Sign in and select the
"Optimum Extras" icon.
3. Select "Manage Dynamic DNS" and
follow the instructions provided.
