Test Account Dyn Help Center

To avoid your own accounts and hostnames becoming blocked when developing a client, the test account and test hostnames have been provided for client testing during the development process. The test account or any of the test hostnames cannot be a default within a client.

The username for the test account is simply test, and the password is also test.

The available test hostnames for Dynamic DNS are:

test.dyndns.org
test.ath.cx
test.dnsalias.net
test.dnsalias.org
test.dnsalias.com
test.homeip.net
test.mine.nu
test.merseine.nu
test.shacknet.nu

The available test hostnames for Dyn Standard DNS are:

test1.customtest.dyndns.org
test2.customtest.dyndns.org
test3.customtest.dyndns.org
test4.customtest.dyndns.org
test5.customtest.dyndns.org
test6.customtest.dyndns.org
test7.customtest.dyndns.org
test8.customtest.dyndns.org
test9.customtest.dyndns.org

Those hostnames are regularly unblocked; if one of them is blocked for update abuse, use another one.

To prevent abuse, the test account cannot be used to log into the website.
