Our service allows you to publish and manage DNS records on a central nameserver through a secure web portal. It is supported by secondary nameservers to provide high availability.
The nameservers are all situated on the Janet network backbone and are geographically separated as a precaution against risks such as fire or network connection failure.
Available to Janet-connected customers at no additional cost
Continuous visibility of web presence and email even if your internet connection is down
Flexible service options: host your full DNS records or a subdomain
Centrally managed service with lower overheads
Reliable and resilient
Supports both IPv4 and IPv6
Self service portal
Organisations using the service can now request access to a secure web portal to edit your resource records and schedule changes at any time.
The web interface also offers organisations:
Backup nameserver Your organisations can run your own local nameserver, using the nameserver as a slave. This means that the nameserver would always have a current copy of your zone; so in the event of the local nameserver becoming unavailable, your authorised administrators could access the nameserver via the web portal, and assign that to become your master nameserver.
Automatic failover Setting specially crafted TXT records on the primary nameserver will cause it to monitor the associated IP address. In the event that the monitored IP address becomes inaccessible, it could either drop the address or failover to an alternate address until the original address becomes accessible again.
The service is available at no additional cost to organisations connected to the Janet network and will help support those customers who do not wish to maintain a full DNS service themselves, or who have certain specific needs.
If you believe that your organisation's email or web services are not working properly, we recommend that you contact your service provider to help diagnose exactly where the problem lies.
Some organisations may not wish to delegate their entire domain to the primary DNS service, but still want to benefit from using the automatic failover feature and/or be able to redirect selected records in the event that their primary domain becomes unavailable.
One option that could allow you to achieve this is to delegate a subdomain to the primary DNS service, and populate that with the address records that need to fail over or be manually managed in the event the primary DNS server fails.
This subdomain would be mastered on the DNS web portal in the normal way. It should probably only be populated with IPv4 and IPv6 address records, and failover TXT records.
A service to allow eligible organisations to publish and manage their public DNS records on a central name server through a secure web portal or to request Jisc to make changes for them.
