Implement WHOIS / registry info search page on get.gov

[gabydisarli]

Story

A WHOIS search feature needs to be added on a new page in get.gov/domains/whois.

Acceptance Criteria

• A new page for WHOIS search is added under /domains
• When the user searches a domain that is registered, they are shown WHOIS data.
• Certain data points are pulled from the raw data and styled according to the mockup. Registrar info (Name, Security email, Whois server, Status; Dates (Created, Expires, Updated), Name servers (list name servers + IPs inside of parentheses)
• User can only search .gov domains. If they search another TLD, like example.com, they are shown the error: "You can only search in domain names that end in .gov"
• If user searches domain that isn't registered, they see the blue info alert: "<domain.gov> isn't a registered domain"
• Below search field, there's a line: "Want to see if a domain is available? Check availability here.
• On get.gov/domains/choosing, add a link to the unavailable error message: That domain isn’t available. [Learn about this domain.](link to WHOIS search results for that domain) <- see Figma

For devs:
You could use a package from online to help with whois as there are a few. However, if you don't find one that's reliable, you could send the whois message and either parse into a json or do string search to find the values that need to display at the top. Then show the full string output for the full whois section. While string search is not great, for a few values it may be reasonable to do if json seems to difficult.

While not many of these node packages for whois are well maintained, you could use their code as examples for writing your own as most are a single file for executing this function.

Note on difficulty, please keep prod team updated if blockers or issues arise that slow this down
Below is a 5 mins js function to retreive whois, this is just an example of how to get whois and retrieve the data as string without any third party dependencies. note net comes with node.

You may copy the below code into a .js, such as whois.js file then run "node whois.js" in terminal.

const net = require('net');

//dumb constant just for illustration purposes
const domain = 'gsa.gov';

// Define the Cloudflare's WHOIS server
const whoisServer = 'whois.dotgov.gov';

// Function to send WHOIS query
function sendWhoisQuery(domain, server, callback) {
    const client = net.createConnection({ port: 43, host: server }, () => {
        client.write(`${domain}\r\n`);
    });

    let whoisData = '';

    client.on('data', (data) => {
        
        whoisData += data.toString();
    });

    client.on('end', () => {
        callback(null, whoisData);
    });

    client.on('error', (err) => {
        callback(err);
    });
}

// Perform the WHOIS query
sendWhoisQuery(domain, whoisServer, (err, data) => {
    if (err) {
        console.error('Error:', err);
    } else {
        console.log('WHOIS data:', data);
    }
});

"refinement" label added: @abroddrick requested time to review the scope and ACs further before committing this into the sprint. It work may be too large for one sprint. It may need splitting. Currently, it has been story pointed to a 5.

Decision in sprint planning meeting is to keep this ticket in "Ready" until dev analysis is completed.
