Steps to configure DDNS:
1. Configuring a Host List (optional)
The host-list is a list of DDNS servers that are required to receive DDNS updates.
This is configured when there are more than one DDNS providers.
ip host-list test
host 10.10.0.0
...
2. Configuring DDNS Update Support on Interfaces (required)
This is for the router to know which interface needs to perform the update and what
hostname to
send to the DDNS server.
config t
interface ether1 <<< description Connected to the ISP with Dynamic IP address
ip address dhcp
ip ddns update hostname abc.dyndns.org <<<< The address to update
ip ddns update mytest <<< ddns pool created
end
Verify you have the following commands
config t
ip domain lookup
ip name-server x.x.x.x
ip name-server y.y.y.y
end
3. Configuring the Update Method and Interval
(required)
config t
ip ddns update method mytest
http <<<<<<< http update method is used here
add
password@members.dyndns.org/nic/update?system=dyndns&hostname')">http://username:password@members.dyndns.org/nic/update?system=dyndns&hostname=&my
ip= <<<<<<
HERE ONLY CHANGE YOUR USERNAME/PASSWORD
interval maximum 1 0 0 0 (dd/hh/mm/sec)
end
NOTE: control v before the ? (else it will think you mean help)
If you don't have a dynamic server you can use a public one. To register on the public
DDNS server:
