In order to be able to manage your DNS via ClusterCS you have you go your Domain > Manage > Edit > Check Enable DNS Management > Save
Additional if you want to use our DNS servers be sure to also check Webland Cluster (dns1.webland.ro / dns2.webland.ro)
When it comes to your DNS zone, ClusterCS creates records automatically for your Domain / www.Domain / Alias / Mail / Webmail
Default records created by ClusterCS:
@ IP 38400 – Name of the domain that is placed in ClusterCS (the actual domain)
mail IP 38400 – A record for mail.domain which is used by the MX type records
www– Each site can have a www or non-www version. This record is made so that it redirects to your domain regardless
webmail – A standard record for the Webmail inferface
MX– When a mail is being sent externally it will lookup the MX Records which point to a certain domain or sub-domain
*Any record in “Points to” that doesn’t end in a dot . is auto-completed with the name of the domain.
Types of DNS:
A – Address record: returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but it is also used for DNSBLs, storing subnet masks in RFC 1101, etc.
AAAA – IPv6 address record: Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host.
CNAME – Canonical name record: Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name.
MX – Mail exchange record: Maps a domain name to a list of message transfer agents for that domain
TXT – Text record: Originally for arbitrary human-readable text in a DNS record. Since the early 1990s, however, this record more often carries machine-readable data, such as specified by RFC 1464, opportunistic encryption, Sender Policy Framework, DKIM, DMARC, DNS-SD, etc.
NS – Name server record: Delegates a DNS zone to use the given authoritative name servers
