CNAME Record
CNAME
records are integral to your custom domain setup. CNAME
records for your custom domain are not managed by Files.com, because they are for a domain that you control. You will need both administrator access to your Files.com site, as well as access to your account with the DNS provider for your domain (e.g. GoDaddy, NameCheap, Route 53, etc.) to configure CNAME
records.
Configuring Your CNAME Record
Once you have chosen your custom domain, the next step is to set up a CNAME
DNS record with your DNS provider. The CNAME
record's value will depend on whether your custom domain will use an SSL certificate provided by Files.com or your own SSL certificate.
If you plan to use SSL provided by Files.com, your CNAME
record must point at your subdomain address. If you are using your own custom SSL certificate your CNAME
will point to an address that contains your subdomain name in the form s-[subdomain].di.app.files.com
.
We recommend using the shortest allowable TTL
value for your CNAME
record, such as 60
seconds. The DNS performance increase provided by large TTL
values (many systems will default to 14400
seconds, or even 86400
seconds) is negligible compared to the risk of waiting hours or days for addresses to propagate.
