How to check the domain name of an app?

In the era of rapid development of mobile Internet, APP has become an indispensable part of people's lives. However, many users will be curious about a question when using APP: How to check the domain name of APP? Especially when doing website development, operation and maintenance, domain name registration, SEO optimization and other work, it is particularly important to understand the domain name corresponding to APP.

1. How to check the domain name of APP? Understand the relationship between APP and domain name

1. The service behind APP depends on the domain name

Although APP runs on mobile devices, its data interaction, resource call, background communication and other functions almost all rely on remote servers, and most of these servers are accessed through domain names. For example, an e-commerce APP will call interface addresses such as api.xxx.com when logging in, placing orders, and paying. Therefore, to figure out "how to check the domain name of APP?" First, you must understand that APP is essentially calling a set of domain names to complete various functions.

2. Domain name forms in common APPs

The domain names used by many APPs are not homepage domain names, but subdomains designed for interfaces. Common formats include api.brand.com, mobile.brand.com, cdn.brand.com, etc. Some will also call resources through self-built CDN or cloud service domain names, which are all considered domain names actually used by APP.

Understanding these structures will help us answer the question "How to check the domain name of the app?" more clearly.

2. How to check the domain name of the app? Share three commonly used query methods

1. View the domain name of the APP request through the packet capture tool

The most direct method is to use the packet capture tool to analyze the network request of the APP. For example, use tools such as Fiddler, Charles, Wireshark, etc., set up a proxy on the mobile phone after installation, and open the target APP to intercept and analyze all its network requests, in which you can see the specific domain name accessed by the APP.

This method is suitable for developers or technology enthusiasts, and it is the clearest and most accurate way for "How to check the domain name of the app?"

The operation steps are as follows:

Set the mobile network proxy to the address of the computer packet capture tool;

Start the packet capture tool and start monitoring;

Open the APP on the mobile phone and perform some common operations;

2. View the domain name by decompiling the APP installation package

If it is not convenient to capture the package, you can also directly download the installation package of the APP (.apk or .ipa), and then use the decompilation tool (such as JADX, Apktool, etc.) to decompile it, and search for fields containing "http" or ".com" in the source code to find the hard-coded interface domain name or resource link in the APP.

This method requires a certain technical foundation, but it is very effective for studying "How to check the domain name of the app?", especially for viewing some interface addresses or CDN domain names.

3. Assisted query through domain name query tools

In addition to technical means, you can also use the domain name service platform to infer the main domain name or related subdomain name that some APPs may use through keyword search, historical whois, subdomain analysis and other functions. This method is suitable for users who do not have high technical requirements but need to understand domain name information.

For example, by searching for registered domain names related to brand names or APP names, you can analyze whether certain domain names are related to the APP. In addition, if you already know a primary domain name, you can also query its registration information and resolve records to further determine whether the domain name is used for APP business.

3. How to check the domain name of the app? These details are worth noting

1. Some APPs may hide or confuse request information

For security reasons, some APPs may use encrypted transmission, HTTPS certificates, or encrypt domain names. At this time, you may not be able to directly see the real domain name through packet capture. In this case, you can configure SSL decryption at the mobile phone system level, or use a jailbroken (Root) device to capture more complete data.

Even so, most mainstream APPs still use regular domain names when communicating with interfaces. How to check the domain name of the app? The key lies in mastering the right tools and analysis skills.

2. Different versions of APP may use different domain names

In actual operation, it is found that some APPs may change the interface address in the new and old versions, such as migrating from a self-built server to a third-party cloud platform, or changing the brand's primary domain name. At this time, the query domain name also needs to be analyzed for different versions, and do not draw conclusions based on the data of only one version.

For example, an APP used abc-app.com in the early stage, and later the brand was upgraded to abcpro.com. At this time, using the domain name history tool to compare whois records is a very effective auxiliary means.

4. The value behind the domain name and APP: not only technology, but also assets

1. Enterprise APP domain name is brand asset

For enterprises, the domain name bound to an APP is not only an entrance, but also an extension of its online brand image. A high-quality, simple, and highly consistent domain name with the brand can make the APP more professional and trustworthy. For example, many well-known APPs will register a primary domain name that is highly related to their brand name, and use it for official websites, download pages, API interfaces, etc. to form a unified image.

Therefore, "How to check the domain name of an app?" is not only to know the technical information behind it, but also to evaluate the brand value and market potential of the domain name.

2. Domain name query provides a reference for registration

On the platform, users often look for related unregistered domain names based on APP or brand names for investment or brand protection. By querying the domain name currently used by the APP, you can infer the domain name that the enterprise has not yet deployed, so as to register or preemptively register it in advance to avoid future price increases.

For example, a company APP uses xypay.com, but xyapp.com has not yet been registered. At this time, through domain name query analysis, you can know its potential and deploy it in advance. This is the value of the domain name preemptive registration business.
