The up-to-date list of plans is available on our [pricing page](https://www.exoscale.com/pricing/#/dns). Form the main Portal navigation, click on **DNS**. Select one of the zone bundles, depending on the number of DNS zones you want to manage. You can upgrade or downgrade your subscription at any time. ![](zone-bundles.png "List of zone bundles") ## Registering domains Exoscale has no way to register domains. You will need to buy domains from an external registrar. After you have configured your zone (either through our API or the Portal) you will need to adjust the NS servers for your zone with your registrar. ## DNS configuration We have collected [a few examples](https://community.exoscale.com/product/networking/dns/how-to/config-examples/index.md) of how you might configure your DNS records. --- url: https://community.exoscale.com/product/networking/dns/overview/ --- # Overview - DNS The DNS service supports the following record types with standard and extra types. ## Standard DNS record types | Type | Portal | API or CLI | Description | | ------- | --- | --- | --- | | A | X | X | Add an "A" record that points your domain or a subdomain to an IP address. | AAAA | X | X | Add an "AAAA" record that points your domain to an IPv6 address. These records are the same as A records except they use IPv6 addresses. | CAA | | X | Add a "CAA" record to your domain. Certification Authority Authorization (CAA) record is used to specify which certificate authorities (CAs) are allowed to issue certificates for a domain. Transferring CAA records to secondary name servers is not supported. | CNAME | X | X | Add a "CNAME" record that aliases a subdomain to another host. These types of records are used when a server is reached by several names. Only use CNAME records on subdomains. | HINFO | X | X | Add an "HINFO" record is used to describe the CPU and OS of a host. | MX | X | X | Add a mail exchange record that points to a mail server or relay. These types of records are used to describe which servers handle incoming email. | NAPTR | X | X | Add an "NAPTR" record to provide a means to map a resource that is not in the domain name syntax to a label that is. More information can be found in RFC 2915. | NS | X | X | Add an "NS" record the delegates a domain to another name server. You may only delegate subdomains (for example subdomain.yourdomain.com). | SPF | X | X | Add an "SPF" record to indicate what hosts and addresses are allowed to send mail from your domain. When creating an SPF record we will automatically create a corresponding TXT record for you as some older mail exchanges require a TXT version of the SPF record. | SRV | X | X | Add an "SRV" record to specify the location of servers for a specific service. | SSHFP | X | X | Edit an "SSHFP" record to share your SSH fingerprint with others. | TXT | X | X | Add a "TXT" record. This is useful for domain records that are not covered by the standard record types. For example, Google uses this type of record for domain verification. ## Extra DNS record types | Type | Portal | API or CLI | Description | | ------- | --- | --- | --- | | URL | X | X | Add an URL redirection record that points your domain to a URL. This type of record uses an HTTP redirect to redirect visitors from a domain to a web site. | POOL | X | X | Add a "POOL" record that aliases a subdomain to another host as part of a pool of available CNAME records. This is a DNSimple custom record type. | ALIAS | X | X | Add an "ALIAS" record. An ALIAS record is a special record that will map a domain to another domain transparently. It can be used like a CNAME but for a name with other records, like the root. When the record is resolved it will look up the A records for the aliased domain and return those as the records for the record name. Note: If you want to redirect to a URL, use a URL record instead. --- url: https://community.exoscale.com/product/networking/dns/how-to/ --- # How-To - DNS Step-by-step guides to configure the service and use specific features, with clear instructions for common tasks and problem solving. - [Configure DNS Zones](https://community.exoscale.com/product/networking/dns/how-to/config-dns/index.md) - Configure DNS zones in the Exoscale Portal by adding domains, managing records, and setting registrar name servers correctly. - [Use DNS Record Examples](https://community.exoscale.com/product/networking/dns/how-to/config-examples/index.md) - Use DNS record examples to add A, CNAME, and MX records, including root domain records that point directly to an IP address. --- url: https://community.exoscale.com/product/networking/dns/how-to/config-dns/ --- # Configure DNS Zones The Portal for our DNS service lets you manage all aspects of your DNS zone. We assume for this guide that you have already chosen a zone bundle. If you have not chosen a zone bundle yet, refer to the [quickstart](https://community.exoscale.com/product/networking/dns/quick-start/index.md) to select one. ## Configuring a Zone via the Portal Enter your domain name in the `Add a Domain` form and click on `Add` to add a name to the domains list. If the status bar turns red, you cannot manage more domains. To add more domains you need to upgrade your subscription to a [larger plan](https://community.exoscale.com/product/networking/dns/quick-start/index.md). Your domain name appears in the list of managed domains. Click on the domain name to display its records. ## Configuring a Domain with a Registrar Before going any further with the zone configuration, check the domain name configuration with your registrar. The name servers should be set to the NS records showing on the Exoscale Portal. If the NS record is not set, any records you set up in the Portal will not be used. ![Default NS records](dns-default.png) --- url: https://community.exoscale.com/product/networking/dns/how-to/config-examples/ --- # Use DNS Record Examples ## Configure a machine record * click on the `Add Record` button at the top right of the header * Select the record type `A` * Enter a name * Enter the IP address of the server * Change the TTL value if necessary * Click on `Add` A toaster/pop-up will indicate that the record has been added successfully. You can continue adding records to the zone. ## Configure an alias record * Select the record type `CNAME` * Enter a name * Enter the targeted subdomain * Change the TTL value if necessary * Click on `Add` ## Configure a Mail Exchange record * Select the record type `MX` * Enter a name * Enter the mail server host * Enter the priority * Change the TTL value if necessary * Click on `Add` ## Configure domain point to an IP In some cases, you need a domain to point to an IP. For instance, you want the domain `example.com` to point to 10.0.13.37 with an A record. * Click on the `Add Record` button at the top right of the header * Select the record type `A` * Leave the name **blank** * Enter the IP address of the server * Change the TTL value if necessary * click on `Add` --- url: https://community.exoscale.com/product/networking/dns/service-boundaries/ --- # Service Boundaries - DNS - [Limits and Quotas - DNS](https://community.exoscale.com/product/networking/dns/service-boundaries/limits-and-quotas/index.md) - DNS Limitations and Quotas - [SLA - DNS](https://community.exoscale.com/product/networking/dns/service-boundaries/sla/index.md) - DNS Service Level Agreement - [Pricing ↗︎](https://www.exoscale.com/pricing/#dns) --- url: https://community.exoscale.com/product/networking/dns/service-boundaries/limits-and-quotas/ --- # Limits and Quotas - DNS ## Limits | Usage | Limit | | -------------------------------------------------------- | ---------------------------- | | Max DNS Records per zone | 1000 | ## Quotas | Usage | Quota | | -------------------------------------------------------- | ---------------------------- | | Zone Count | 1, 10, 50, multiples of 50 | ## Availability DNS is available in all zones. --- url: https://community.exoscale.com/product/networking/dns/service-boundaries/sla/ --- # SLA - DNS ## DNS Service Level Agreement (SLA) These product-specific SLAs define the Service Availability Target for the Domain Name System (DNS) service.
