Typical DNS Records

D('example.com', REG, DnsProvider('GCLOUD'),
    A('@', ''),  // The naked or 'apex' domain.
    A('server1', ''),
    AAAA('wide', '2001:0db8:85a3:0000:0000:8a2e:0370:7334'),
    CNAME('www', 'server1'),
    CNAME('another', 'service.mycloud.com.'),
    MX('mail', 10, 'mailserver'),
    MX('mail', 20, 'mailqueue'),
    TXT('the', 'message'),
    NS('delegated', 'ns1.dnsexample.com.'),
    NS('delegated', 'ns2.dnsexample.com.')

Set TTLs

D('example.com', registrar,
    DefaultTTL(400), // Default for a domain
    A('@', '', TTL(400)), // individual record
    {'ns_ttl': '400'} // On domain apex NS RRs

Variables for common IP Addresses

var addrA = IP('')

D('example.com', REG, DnsProvider('R53'),
    A('@', addrA), //
    A('www', addrA + 1), //

Variables to swap active Data Center

var dcA = IP('');
var dcB = IP('');

// switch to dcB to failover
var activeDC = dcA;

D('example.com', REG, DnsProvider('R53'),
    A('@', activeDC + 5), // fixed address based on activeDC

Macro to for repeated records

    MX('@', 1, 'aspmx.l.google.com.'),
    MX('@', 5, 'alt1.aspmx.l.google.com.'),
    MX('@', 5, 'alt2.aspmx.l.google.com.'),
    MX('@', 10, 'alt3.aspmx.l.google.com.'),
    MX('@', 10, 'alt4.aspmx.l.google.com.'),
    CNAME('calendar', 'ghs.googlehosted.com.'),
    CNAME('drive', 'ghs.googlehosted.com.'),
    CNAME('mail', 'ghs.googlehosted.com.'),
    CNAME('groups', 'ghs.googlehosted.com.'),
    CNAME('sites', 'ghs.googlehosted.com.'),
    CNAME('start', 'ghs.googlehosted.com.'),

D('example.com', REG, DnsProvider('R53'),
   A('@', '')

Add comments along complex SPF records

You normally can’t put comments in the middle of a string, but with a little bit of creativity you can document each element of an SPF record this way.

var SPF_RECORDS = TXT('@', [
    'ip4:',           // NY mail server
    'ip4:',           // CO mail server
    'include:_spf.google.com',  // Google Apps
    'include:mailgun.org',      // Mailgun (requested by Ticket#12345)
    'include:servers.mcsv.net', // MailChimp (requested by Ticket#54321)
    'include:sendgrid.net',     // SendGrid (requested by Ticket#23456)
    'include:spf.mtasv.net',    // Desk.com (needed by IT team)
].join(' '));

D('example.com', REG, DnsProvider('R53'),

Dual DNS Providers

D('example.com', REG, DnsProvider('R53'), DnsProvider('GCLOUD'),
   A('@', '')

// above zone uses 8 NS records total (4 from each provider dynamically gathered)
// below zone will only take 2 from each for a total of 4. May be better for performance reasons.

D('example2.com', REG, DnsProvider('R53',2), DnsProvider('GCLOUD',2),
   A('@', '')

// or set a Provider as a non-authoritative backup (don't register its nameservers)
D('example3.com', REG, DnsProvider('R53'), DnsProvider('GCLOUD',0),
   A('@', '')
