## 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.
## Use SPF_BUILDER to add comments along SPF records
```javascript
var SPF_RECORDS = TXT('@', [
'v=spf1',
'ip4:1.2.3.0/24', // NY mail server
'ip4:4.3.2.0/24', // 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)
'~all'
].join(' '));
D('example.com', REG, DnsProvider('R53'),
SPF_RECORDS,
)
D("example.tld", REG, DSP, ...
A("@", "10.2.2.2"),
MX("@", "example.tld."),
SPF_BUILDER({
label: "@",
overflow: "_spf%d",
raw: "_rawspf",
ttl: "5m",
parts: [
"v=spf1",
"ip4:198.252.206.0/24", // ny-mail*
"ip4:192.111.0.0/24", // co-mail*
"include:_spf.google.com", // GSuite
"~all"
]
}),
);
```
