A DNS zone is a portion of the global DNS namespace for which administrative responsibility has been delegated. In most cases, your DNS zone is your domain name (i.e. example.com)
When creating a new DNS zone at DurableDNS you need to provide the following information (in most cases the default values are acceptable):
Zone Name – This is usually the name of your domain, like example.com. But it could also be a sub-domain, like sub.example.com.
Primary Nameserver – This is the master nameserver for your zone. Usually you would leave the default value of “ns1.durabledns.com.” here unless DurableDNS is going to act as secondary
DNS to another nameserver you manage.
Responsible Person Mailbox – This is the email address of the person responsible for this
DNS zone. The email address must be in “
DNS format” which means that you need to replace the '@' with a '.'.
Refresh – This is the amount of time, in seconds, that secondary nameservers should wait before refreshing their copy of this zone. This is only used if you have non-DurableDNS nameservers that retrieve data from DurableDNS.
Expire – This is the amount of time, in seconds, that secondary nameservers should wait before deleting their copy of this zone if they have been unable to update from the primary nameserver. This is only used if you have non-DurableDNS nameservers that retrieve data from DurableDNS.
Minimum Time-to-live for Records – This is the minimum allowed TTL value for records in this zone, in seconds. If a record has a TTL lower than this value, the
DNS servers will respond with this value.
Zone Time-to-live – This is the amount of time, in seconds, that resolving
DNS servers and
DNS clients are allowed to cache this zone.
AXFR Zone Transfer Allow List – This is a list of IP addresses or IP address ranges that are allowed to download this zone from DurableDNS via AXFR. This is only used if you have non-DurableDNS nameservers for this zone and DurableDNS is the master
DNS server.
DDNS Update Allow List – This is a list of IP address or IP address ranges that are allowed to update records via DDNS. This is not commonly used.
