Your DNS providers.
One update for all.

Keep the DNS providers and records you already use. Your router sends one request to DNSbun when your IP changes, and we relay the new IP to each destination. Your services stay up to date together.

HOW IT WORKS

Your services, updated together.

Choose the services you already use. Send one update through DNSbun. The same services receive your new IP.

01

Choose your services

Connect the DNS providers and records you already use. Your domains stay where they are.

02

Send one update

Your router sends the new IP to DNSbun once. We relay it to every service you selected.

03

Your services are updated

The same providers receive your new IP. Check the result for each destination in one place.

BUILT FOR THE REAL INTERNET

Dynamic IPs.
Steady infrastructure.

Your IP may move around. Your services shouldn’t feel it. DNSbun adds the reliability and visibility your router was missing.

Every update, accounted for

See what changed, where it went, and how every provider responded.
