Set up an email address with your own .at domain
An address such as office@yourname.at needs a domain and an email service. Learn what the mailbox, MX, SPF, DKIM and DMARC each do.
Read guide ↗The essentials
A and AAAA connect names to IP addresses, CNAME points to another name, MX directs incoming mail and TXT stores verification values. Edit records where the domain’s active nameservers are managed.
A and AAAA: your website address
An A record maps a hostname to an IPv4 address. AAAA does the same for IPv6. Your hosting provider supplies the destination. For the root domain, interfaces commonly use @ or an empty host field. Creating a root record does not automatically create a matching www record. The values below are documentation examples only. Use the actual instructions from your website service for your domain.
| Type | Host | Example value |
|---|---|---|
| A | @ | 192.0.2.10 |
| AAAA | @ | 2001:db8::10 |
| CNAME | www | website.example.net |
CNAME: one name points to another
A CNAME aliases one hostname to another. Many website services request a CNAME for www. Enter a hostname, not a URL with https:// or a path. A CNAME cannot normally coexist with other record types at the same name. Additional restrictions apply at the zone root.
MX and TXT: email and verification
MX specifies the servers that receive mail for a domain. Priority orders multiple servers; lower numbers take precedence. TXT stores text and is used for service verification, SPF and DKIM. Copy values exactly from your email provider’s instructions. A DNS record does not create a mailbox.
Set up your own email address ↗TTL and the correct DNS zone
TTL sets how long a DNS result may be cached. Changes therefore do not appear everywhere at once. If you use external nameservers, edit records at that DNS provider. Changes in the DNS zone in your atdomain.at account only affect resolution when the domain uses those nameservers.
