COM.BR - Preconfigured Nameservers

The Registro.br requires that name servers are properly preconfigured before delegating the domain. This rule applies to both domain registrations and domain updates replacing name servers.

Technical name server requirements

For COM.BR domains, the presence of the SOA record and NS records will suffice, if properly preconfigured. However, the full list of types of error messages can be found at:

Registry-Based Check

The registry provides a web-based tool to check the DNS setup for a domain, in Brazilian Portuguese. The test shows whether there are setup errors for one or more name servers:

Internal Check

You can also check the name servers with the CheckDNS command. For example:

command=checkdns
domain=example.com.br
nameserver0=ns1.nameserver.com
nameserver1=ns2.othernameserver.com
