Okay I asked the support and got the following answer:
*You can use as many CNAMEs as you wish. There is no limit.
Our DNS is a free DNS service, as long as you have droplets with us.*
I recommend adding a wildcard CNAME record instead as it scales better than thousands of records:
This makes everything under yourdomain.com (such as user1.yourdomain.com, user2.yourdomain.com, something.user1.yourdomain.com, etc.) point to the same hostname which is yourdomain.com. in the screenshot.
Hey Kamaln
Thanks for you idea which is cool for many scenarios but doesnt work in my case ;).
The Cname Mappings look like the following example ;)
username.mydomain.com -> id1.external.com.
Anotherusername.mydomain.com -> id2.external.com.
An automatic wildcard just isnt possible.
Thousands of records is a very large amount, so in that case I'd suggest setting up your own nameservers as it would be easier to manage that way or using a paid DNS service such as Amazon Route53, DNSSimple, DNSMadeEasy, etc.. You can use PowerDNS (How To Install PowerDNS on CentOS 6.3 x64 | DigitalOcean) which allows you to store DNS records in a MySQL table so it'd be relatively painless to manage.
Thanks again, but Really: why should i? Digitalocean has a really nice api, I dont need own Nameservers. I just asked if there are any quantity limitations...
it don't worked to me, I'm trying it about one week, I have two domains in one droplet.
domain one is like this
@ IN A IP-ADRESS
www CNAME @
and other is this
@ IN A IP-ADRESS
but is i try *.sitesradio.com.br it doesn't work execpt is is www. so it work in the other domain only work with www.domain,com (it's ok to this case)
