A DNS portal is a web-based interface that provides access to manage and configure Domain Name System (DNS) settings. Different platforms offer varying levels of functionality, but generally, they allow users to create, update, and delete DNS records, zones, and other related settings.
Types and Uses of DNS Portals
The exact functionality of a DNS portal depends heavily on the platform it's associated with. Here are some examples:
-
Cloud Provider Portals (e.g., Azure, AWS): These portals offer integrated DNS management services within their cloud ecosystems. You can create and manage DNS zones directly within the portal, often linked to other cloud resources like virtual machines or web applications. An example is Azure's DNS portal (https://portal.azure.com/#view/HubsExtension/BrowseResource/resourceType/Microsoft.Network%2FdnsZones), allowing users to see and manage their DNS zones.
-
On-Premise DNS Management: Some organizations utilize internal DNS servers with dedicated management portals, offering control over their internal DNS infrastructure.
-
Specialized DNS Services: Some DNS services offer specific portals designed for technical accreditation, as in the case of the DNS portal offering a platform for technical accreditation with OT&E servers for ZA SLDs, gTLDs and other ccTLDs within the DNS service, providing a centralized platform for multiple namespace accreditations.
-
Captive Portal DNS Management: In situations like public Wi-Fi hotspots, a captive portal might require specific DNS configurations to direct users to a login page. This usually involves configuring the DHCP server to provide specific DNS addresses or allow users to utilize any public DNS server as a workaround (https://forum.netgate.com/topic/71251/whitelisting-forwarding-dns-for-captive-portal-users-solved). Issues can arise, such as slow DNS resolution times (https://community.sophos.com/sophos-xg-firewall/f/discussions/90889/dns-not-resolve-while-using-captive-portal) or the portal redirecting incorrectly (https://community.esri.com/t5/arcgis-enterprise-questions/portal-redirecting-away-from-dns-alias-to-hostname/td-p/630548/page/2).
It is crucial to understand that the term "DNS portal" lacks a universally standardized definition. Its meaning is derived from the context in which it's used. The common thread is its role as a user interface to control DNS settings, with the specifics dictated by the system it serves.
