[YiGeRen-yl]

允许的IP是否可以改成域名的形式

[brendanosborne]

The translated question from Chinese to English:
Whether the allowed IP can be changed to the form of domain name

Reply:
Hi, it can be added as a feature but need to consider how the domain name changes the IP address.

Translated to Chinese:
您好，它可以作为一项功能添加，但需要考虑域名如何更改 IP 地址。
