Control over your zone

Your DNS zone has a command line.

Create records, export zones, switch DNSSEC on. Through a documented HTTP interface, through MCP tools for agents or straight from your router.

Agents work with your permissions.

Install, confirm in the browser, ask. You decide which permissions an agent gets, and take them back one at a time.

30tools in the catalogue

dns:read11
dns:write7
domain:read5
domain:write3
hosting:read4

You grant permissions at sign-in and revoke them per client, without touching any other access.
Write tools are rate-limited and audited; unusual patterns lock automatically.
Registering, transferring or cancelling domains deliberately does not work through the interface, everything with payment impact stays in the dash.
Passwords and other secrets are never returned by the API.

DNS API docs

DNSSEC

Free feature

Signed DNS zones without extra complexity. Resolvers detect forged or manipulated answers immediately.

Signed zoneDNSKEY, RRSIG and authentic answers
Delegation at the registryThe DS record links the parent zone securely
Validation at the resolverOnly genuine answers are accepted

Sign directly on the regfish nameservers, or keep your existing external DNS and delegate cleanly with a DS record.

About DNSSEC

DynDNS

Free feature

Keep dynamic IPs updated automatically, ideal for home servers and VPN. Enable DynDNS, get a token, send updates.

curl 'https://dyndns.regfish.de/?fqdn=home.example.com&token=YOUR_DYNDNS_TOKEN'

Response codes

100Update applied
101No update needed

Works with Fritz!Box, Synology, QNAP and more. IPv4 and IPv6 are both fully supported.

Set up DynDNS

Bookable on top

What happens while you are not looking.

What you do yourself stays free. The platform plans take over what has to keep running when nobody is looking at the dashboard: watching, warning, keeping records.

Pro

Never lose a domain

The guardian alerts you when a transfer lock drops or someone requests an auth code. The code itself sits in the vault, not in the mailbox of someone who left the company long ago.

Pro

Rules, not trust

Define what nobody may change on your domains without approval: nameservers, transfer lock, critical records. Two-factor sign-in is enforced across every login on the account.

Pro

Every change on record

Every change to your zones is logged with timestamp, account and previous value. Critical records trigger an alert straight away, not at the next outage.

Pro

Your zones, always checked

The DNS doctor checks SPF, DKIM, DMARC, DNSSEC and propagation continuously. You get the finding in plain language and the finished record along with it.

Business

Nameservers with your name

Your zones answer under ns1.yourcompany.com instead of our address. Clients see your brand in the delegation. One set of nameservers covers every zone.

Business

See who is asking

Where the queries to your zone come from, which records get pulled and when load peaks hit. On a world map and over time.

from €9.00 per month, for all your domains and not per domain.
