dns

Dev channel

To use this API, you must declare the "dns" permission in the manifest.

{
"name":"My extension",
...
"permissions":[
"dns"
],
...
}

The following code calls resolve() to retrieve the IP address of example.com.

service-worker.js:

constresolveDNS=async()=>{
letrecord=awaitchrome.dns.resolve('example.com');
console.log(record.address);// "192.0.2.172"
};
resolveDNS();

Key point: Do not include the scheme or trailing slash in the hostname. For example, https://example.com/ is invalid.

chrome.dns.resolve(
