What is DNS-O-Matic?

DNS-O-Matic is a total free of cost service from OpenDNS. DNS-O-Matic provides you a free and easy way to announce your dynamic IP changes to multiple services with a single update. Using DNS-O-Matic allows you to pick and choose what Dynamic DNS services you want to notify.

Why DNS-O-Matic?

Many applications on the Internet rely on knowing your IP address. Providing a scalable platform to allow people to selectively announce when their IP address changes will benefit all sorts of services and applications. And, this isn't just about DNS — everything from your Apple TV to your Xbox 360 can benefit from knowing when your IP changes.

Does DNS-O-Matic provide hostnames or other DNS services?

No. DNS-O-Matic does one thing very well: distributes dynamic IP updates to all your chosen services. You just update your IP (with custom settings on DDNS tab of your ddwrt router) at DNS-O-MATIC, and DNS-O-MATIC will send updated information to all yours dns providers at the same time.

For example if you use:

1) OpenDNS to webfilter your Guest WiFi

2) DtDNS where you have free FQDN (if you are using ddwrt as a VPN server on Dynamic IP, it is more easier to remember domain ‘cause IP changes all the time)

3) Tunnelbroker and 6in4 Static Tunnel

you can update them all at once.

Does DNS-O-Matic cost any money? No. DNS-O-Matic is free.

Is my information secure with DNS-O-Matic? Yes. DNS-O-Matic account creation and service provision is handled under Secure Sockets Layer (SSL) encryption. DNS-O-Matic does not store any passwords in plaintext. Where available, DNS-O-Matic suggests using a service's update credentials rather than account credentials. Currently, dd-wrt uses INADYN without https support because of lack of flashspace on most units.

Before proceeding next steps make sure that you use DNS-O-MATIC as your default DDNS service on dd-wrt unit. For configuring see OpenDNS with DNS-O-Matic for users with a Dynamic IP section.

Configuring Tunnelbroker on DNS-O-Matic

If you have checked Block Anonymous WAN Requests (ping) on Security/Firewall tab then you have to make your dd-wrt router pingable from HE server. To do so save this as your firewall rule on Administration/Command tab:

iptables -I INPUT 2 -s -p icmp -j ACCEPT

First login to your DNS-O-MATIC account. You can use your OpenDNS credentials to login. Click on Add a service and choose Tunnelbroker. You will see 3 blank fields User ID, Passwor and Host/Identifier.

User ID: Your Tunnelbroker Username (Account Name), the one you use to log in, not your long hashy User ID as suggested elsewhere.

Password: The Update Key from your tunnel’s information page.

Host/Identifier: The DNS fully-qualified name of your tunnel, not the numeric Tunnel ID. This is of the form <user>-<index>.tunnel.<tunnel-server>.<datacenter>.ipv6.he.net.

Fil in, save and than reboot your router to get new IP.
