Overview

Enterprise Mobile Application Studio HTTPDNS is a domain name resolution service for apps on multiple types of platforms, such as mobile apps and desktop apps. After your app directly accesses HTTPDNS or accesses HTTPDNS using an SDK, HTTPDNS obtains the IP address with the lowest access latency configured for the business in DNS and sends a request to the IP address. This reduces the latency of domain name resolution to milliseconds. Enterprise Mobile Application Studio HTTPDNS resolves domain names over HTTP or HTTPS. Compared with traditional domain name resolution services, HTTPDNS is improved in the protection against domain hijacking, the accuracy and stability of resolution, and the timeliness of updating resolution results. HTTPDNS ensures 99.99% service availability and can be used for domain name resolution regardless of whether the domain name is registered with or hosted by Alibaba Cloud.

Protection Against Domain Hijacking

DNS resolution requests are sent directly to the HTTPDNS server, bypassing the local DNS servers of Internet service providers (ISPs). This can prevent domain hijacking.

Precise Scheduling

Enterprise Mobile Application Studio HTTPDNS accurately determines the region where a client resides based on the originating IP address of the client. This facilitates precise scheduling and provides nearby access to clients.

Quick Updates of Resolution Results

Enterprise Mobile Application Studio HTTPDNS interacts with your authoritative name server strictly based on the specified time to live (TTL) period to synchronize changed resolution results from your authoritative name server to HTTPDNS quickly.

Features

Secure and Accurate Resolution Results

Protection Against Domain Hijacking DNS resolution requests are sent directly to the HTTPDNS server, bypassing the local DNS servers of ISPs. This can prevent domain hijacking. Accurate Resolution Results Enterprise Mobile Application Studio HTTPDNS can obtain the egress gateway IP addresses of clients. This allows it to accurately determine the region where a client resides and the corresponding ISP and provide accurate resolution results. High Availability Enterprise Mobile Application Studio HTTPDNS can effectively alleviate the risk of an app becoming unavailable due to uncertainties in ISP networks and improve the success rate of resolution in poor wireless network environments.

Network-Wide Domain Name Resolution

Network-Wide Domain Name Resolution Enterprise Mobile Application Studio HTTPDNS resolves network-wide domain names, including those registered with Alibaba Cloud, third-party registrars in China, and registrars outside China. A domain name registered with a registrar outside China must comply with any region-specific regulations. Resolution of Domain Names Provided by CDN Service Providers Enterprise Mobile Application Studio HTTPDNS resolves domain names registered with registrars (such as Akamai and Cloudflare) and supports precise scheduling in scenarios that involve Content Delivery Network (CDN). HTTPDNS provides SDKs for mobile clients and API operations for various scenarios. Simple API Operations Enterprise Mobile Application Studio HTTPDNS provides simple-to-use API operations. You can call an API operation from a mobile app to resolve the domain name or call an operation from the server side.

Efficient and Cost-Effective Integration

One-Time SDK Integration Enterprise Mobile Application Studio HTTPDNS provides SDKs for Android and iOS mobile clients. The SDKs require one-time integration and allow you to extend your business worldwide without updating repeatedly on the client side. API Integration Enterprise Mobile Application Studio HTTPDNS provides API operations that support HTTP and HTTPS requests. This allows the service to be integrated by other means. Free Quota Enterprise Mobile Application Studio HTTPDNS offers 1.5 million domain name resolutions free of charge each month. You are only charged after the free quota is used completely.

Software-Defined DNS

You can integrate HTTPDNS with Function Compute to customize the resolution process. For example, you can specify custom parameters and their return values, resolution rules, and the lines for resolution. This way, intelligent scheduling and location-based scheduling can be implemented.
