FAQ

We combine our experience in network infrastructure and DNS services into one application.

A subdomain is a name below a domain, such as myname.tux.re. DNS records connect that name to your server or service.

Choose A, AAAA, CNAME, TXT, MX, SRV or CAA. You can add multiple values and child names inside your own subdomain.

TTL is the time a DNS answer may be cached, in seconds. Choose 60–86400 seconds. It is not an expiry date; cached answers may remain until the previous TTL expires.

A CNAME must be the only record type at the same name. Use a separate child name or A and AAAA records when you also need TXT or MX.

DynDNS updates an IP address when it changes. Create a token for a subdomain with a primary A or AAAA record and let a compatible client send updates over HTTPS.

This version updates one primary record per hostname: A for IPv4 or AAAA for IPv6. Use separate subdomains and tokens for independent updates of both families.

DNS only maps names to destinations. Your server still needs its own hosting, firewall rules, port forwarding where necessary and a TLS certificate for HTTPS.

Resolvers and devices may cache the previous answer until its TTL expires. Check the authoritative nameserver first, then your local resolver. DNS changes do not clear existing caches.

Treat the token like a password. Keep it out of shared URLs and screenshots, use HTTPS, and revoke or rotate it in your account if it is exposed.
