We have a number of DNS servers spread across the globe. Read more about our nameservers.
Only one NS Free account is allowed per person. Please upgrade your existing NS Free account to a paid plan instead of attempting to create a second NS Free account.
Yes. Domains, Hosts, and Templates are all supported by a full REST API. See the REST API documentation for details. For very basic updates, we also support dynamic DNS updates. More information is below.
Sure do. Just use '*' for the hostname. By default our name servers will check for an actual host record with the queried name. If that's not present, then it checks for a wildcard record. That means you can effectively use a wildcard record as a catchall.
Zerigo does not offer email forwarding. We do, of course, support just about any possible email configuration via third-party email providers. One popular solution to email forwarding is to use a Google Apps For Your Domain account (which will even let you mix-and-match regular and forwarding addresses).
Yes. Create a DNS host record using our special "Redirect" type. By default, web redirects use HTTP 302 redirects. This may be changed to a 301 redirect or a cloaked redirect under DNS -> Preferences.
No, we are not a domain registrar. We provide DNS services for domains that you've already registered elsewhere.

The hostname field allows nested subdomains. For example, if your domain is 'example.com' and the hostname field is 'www.dealers', then the full, valid domain name would be 'www.dealers.example.com'. You can have even more levels if necessary.
Simply add multiple records. Our system will automatically detect this situation and rotate through the possible responses. For example, create two host records, each with Hostname: www and Type: A, but give them different IPs. Everything else is automatic.
Absolutely. Domain Keys records should be entered using a TXT record type.
SPF records may be entered with the dedicated SPF record type or, for legacy compatibility, with a TXT record. You may create both for maximum compatibility.
We provide full IPv6 support. Our nameservers have native IPv4 and IPv6 connectivity. We also support AAAA records for full lookups as well as reverse domains (ip6.arpa).
Yes, simply add new host records with the NS type.
Our basic, entry-level service really is free. If you require more than basic support, have a higher number of domains, or a higher volume of DNS requests, then you'll need to upgrade. After finding Zerigo DNS useful, we hope you will also consider whether any of our other services might be a good fit too.
Static DNS service is DNS service for static, or consistent, IP addresses. This is by far the most common DNS service—used for pretty much every service (web, email, etc.) across the internet.
Dynamic DNS service is DNS service for dynamic, or changing, IP addresses. Some individuals and small businesses want to run some kind of low-use internet service from their DSL, cable, or other internet connection. The IP address for these connections changes periodically—sometimes every few months, sometimes every few hours or even more often.
If an IP address changes infrequently, it's not too bad to just change the DNS entry—if the TTL (time-to-live) for that address is short (15 minutes or less). Zerigo DNS allows TTLs as low as 1 minute to support this.
For IP addresses that change more often, and sometimes even for those that change infrequently, some kind of software program is run from the target computer that publishes its current IP address—so the update is automatic and timely. Zerigo DNS is capable of receiving this notification and updating the appropriate DNS entry accordingly.
There are two options for making changes to your DNS service without using our web interface. The first is dynamic updates. This is ideal for simple dynamic DNS service. See the Dynamic Updates documentation for details and examples. The second option is our full-featured REST API.
Yes. Our system will automatically look for an AAAA record to update either when accessed via an IPv6 address (and no IP address is specified) or when expressly provided with an IPv6 address.
