Questions, answered
What is dynamic DNS?＋
Home and small-office connections get a new IP whenever the ISP feels like it. Dynamic DNS keeps a fixed hostname pointed at that moving target, so your VPN, NAS, cameras or game server stay reachable at the same name.
Which records can I create?＋
Dynamic A/AAAA records that your router updates automatically, static A/AAAA records you set by hand, and CNAME aliases that point one of your names at any other domain.
Which routers and clients are supported?＋
Anything that speaks the dyndns2 protocol: MikroTik RouterOS, ASUS, pfSense/OPNsense, DD-WRT, ddclient, inadyn — or a one-line curl in a cron job. Guides for each are in the docs.
Is the free tier actually free?＋
Yes — 50 hostnames, all record types, the full API and update history. Paid plans exist for people who need hundreds of names.
