.DESCRIPTION
New-DomainDnsRecord adds a DNS node object to an Active Directory-Integrated DNS (ADIDNS) zone.
.PARAMETER Server
Specifies the domain controller to query.
.PARAMETER SSL
Use SSL connection to LDAP server.
.PARAMETER Credential
Specifies the privileged account to use.
.PARAMETER RecordType
Specifies the DNS record type, defaults to A.
.PARAMETER Name
Specifies the DNS record name.
.PARAMETER Data
Specifies the DNS record data, typically the destination IP address.
.PARAMETER ZoneName
Specifies the DNS zone, defaults to Active Directory domain name.
.PARAMETER Static
Creates a static record instead of a dynamic one.
