On April 10th we will be retiring the old IP address for ns4.dnsimple.com. We've already moved over all DNSimple customers who use ns4.dnsimple.com directly, as well as customers who use a vanity name server where the domain is registered through us. The only remaining name servers to be updated are vanity name servers that are managed by another registrar. If you manage a vanity name server and the domain is hosted at another registrar then you will receive an email today explaining the required change. Just in case you do not receive the email, here is the information you need:

  • The new IPv4 address for ns4 is: 50.112.128.56
  • The IPv6 address for ns4 is: 2001:470:1f0f:9e8::1:1

We want to make this transition as smooth as possible, so if you have any questions please feel free to contact us at support@dnsimple.com.
