Dynamic DNS domain name resolution using Python scripts

This article mainly introduces the Python script to implement dynamic DNS domain name resolution. This article provides the implementation code directly. if you need it, you can refer to your spare time and build your own server at home, because the residential broadband is used, IP addresses are dynamically allocated. Domain name resolution is a problem. my domain name is usually parked under DNSPod. DNSPod provides an API for modification, so it simply implements dynamic parsing using Python. In this way, there is no need to install a peanut shell. If you don't talk nonsense, read the code:
