DNS in Google Sheets

​​ Create a function

1.1.1.1 works directly inside Google Sheets. To get started, create a Google Function with the following code:

function NSLookup(type, domain) {
if (typeof type == 'undefined') {
throw new Error('Missing parameter 1 dns type');
}
if (typeof domain == 'undefined') {
throw new Error('Missing parameter 2 domain name');
}
type = type.toUpperCase();
var url = 'https://cloudflare-dns.com/dns-query?name=' + encodeURIComponent(domain) + '&type=' + encodeURIComponent(type);
var options = {
muteHttpExceptions: true,
headers: {
accept: "application/dns-json"
}
};
var result = UrlFetchApp.fetch(url, options);
var rc = result.getResponseCode();
var resultText = result.getContentText();
if (rc !== 200) {
throw new Error(rc);
}
var errors = [
{ name: "NoError", description: "No Error"}, // 0
{ name: "FormErr", description: "Format Error"}, // 1
{ name: "ServFail", description: "Server Failure"}, // 2
{ name: "NXDomain", description: "Non-Existent Domain"}, // 3
{ name: "NotImp", description: "Not Implemented"}, // 4
{ name: "Refused", description: "Query Refused"}, // 5
{ name: "YXDomain", description: "Name Exists when it should not"}, // 6
{ name: "YXRRSet", description: "RR Set Exists when it should not"}, // 7
{ name: "NXRRSet", description: "RR Set that should exist does not"}, // 8
{ name: "NotAuth", description: "Not Authorized"} // 9
];
var response = JSON.parse(resultText);
if (response.Status !== 0) {
return errors[response.Status].name;
}
var outputData = [];
for (var i in response.Answer) {
outputData.push(response.Answer[i].data);
}
var outputString = outputData.join(',');
return outputString;
}

​​ Using 1.1.1.1

When you feed the function NSLookup a record type and a domain, you will get a DNS record value in the cell you called NSLookup.

Supported DNS record types
  • A
  • AAAA
  • CAA
  • CNAME
  • DS
  • DNSKEY
  • MX
  • NS
  • NSEC
  • NSEC3
  • RRSIG
  • SOA
  • TXT

For example, typing:

NSLookup(B1, B2)
