Frequently Asked Questions

Who created this site, and why was it made?

This site was created by Steve Kemp.

It was created as a learning experience for working with Amazon's Route53 API.

It has been left running since then because I tend to feel bad if I cancel services users rely upon - that said I make no promise that it will remain in service indefinitely.

How long does it take for DNS changes to take effect?

All the records beneath the dhcp.io domain have a 3600 second (one hour) TTL.

That means that while changes will take effect as they are visible you might see the old values for up to an hour.

How do I set only IPv6 or IPv4 addresses?

If the host you're updating from has both IPv4 and IPv6 connectivity you might find you're update the wrong value.

The solution is to explicitly choose which version you wish to update via the -4 and -6 arguments to curl:

        $ # This will update the IPv4 address.
        $ curl -4 https://dhcp.io/set/efa6961c-f3dd-11e3-955b-...

        $ # This will update the IPv6 address.
        $ curl -6 https://dhcp.io/set/efa6961c-f3dd-11e3-955b-...
      

Alternatively you can login and edit the records via your browser.

Is this service free?

Yes it is a free service, although if you do not trust it to remain alive in the future you may clone the source-code from Github, and run your own instance.

The author of this site also runs a system which allows you to host your own DNS zones, which interfaces with the git revision control system:

If you wish to host domains, and don't want to manage the complex API involved it could be just what you're looking for.

How do you cope with abuse?

When abuse-reports are received, if they are judged worthy, the offending account is deleted, including all other records that account held.

My account was deleted, what do I do?

Find a new DNS host.

How do I delete my account?

If you wish to permanently delete your account please visit the profile deletion page.

Can I see my history?

Yes, if you're signed into the site you can visit the logs page, which will show you the most recent 100 changes applied to your record(s).
