SVCB records can be configured by the owner of a domain name. They are used to store information in the DNS, which can be looked up by anyone. Each record type has a different purpose.
SVCB records are configured in DNS. But how can you look up these SVCB records? That depends on the operating system you are using. Windows, Linux and Mac all have a different way of finding SVCB records. The sections below contain instructions for each operating system.
How to lookup SVCB records on Windows
The SVCB record type cannot be looked up in Windows. Neither nslookup, nor Powershell's Resolve-DnsName has support for it. You can either install WSL and follow the Linux instructions below, or use an online SVCB lookup tool like the one on the top of this page.
How to lookup SVCB records on Mac OS
To check the SVCB records for a certain domain name on a Mac, follow these steps:
- Open a terminal by entering [command] + [space] → 'terminal.app' → [enter].
- Type
dig example.com svcband hit [enter] to get the SVCB records forexample.com. - The SVCB records are listed below the ANSWER SECTION heading.
How to lookup SVCB records on Linux
To check the SVCB records for a certain domain name on Linux, follow these steps:
- Open a terminal by entering [Super] → 'terminal' → [enter].
- Type
dig example.com svcband hit [enter] to get the SVCB records forexample.com.
- The SVCB records are listed below the ANSWER SECTION heading.
How to find SVCB records
To check the SVCB records of a domain, follow these steps:
- Open the SVCB lookup tool.
- Enter the domain name and hit [enter].
- The tool will query the SVCB records and shown them at the top of the page.
How to lookup other record types
There are other types of DNS records then just SVCB. The most commonly used DNS record types are A, AAAA, CNAME, NS, TXT, MX and SOA.
