Question 1

How does public-ip compare to just using ipify directly?

Accepted Answer

public-ip combines multiple sources like DNS and HTTPS services for better reliability, whereas using ipify alone is simpler but has a single point of failure. public-ip is ideal for applications needing redundancy.

Question 2

How to handle errors when public-ip fails to find an IP?

Accepted Answer

Catch the IpNotFoundError specifically, as shown in the README. You can also add custom fallbackUrls or check network connectivity before retrying.

Question 3

Can I use public-ip in a React Native app?

Accepted Answer

It supports browsers, so it might work in React Native if the environment supports standard web APIs, but it's not explicitly tested or documented for such use cases.

Question 4

Is public-ip's onlyHttps mode secure enough for banking apps?

Accepted Answer

The onlyHttps mode uses HTTPS for tamper-proof checks, but it's slower. For high-security applications, evaluate the trade-off between speed and security, and ensure fallback services are trusted.

Question 5

How to cancel a public-ip request in a browser?

Accepted Answer

Use the signal option with an AbortSignal. For example, create an AbortController, pass its signal, and call abort() to cancel the request, handling the AbortError as per the README.

Question 6

What if I need to get the IP address very frequently?

Accepted Answer

public-ip doesn't have built-in caching, so frequent calls might hit rate limits on external services. Consider implementing your own caching layer or using a dedicated IP service with higher limits.
