updns

node

updns is a DNS server developed using node, only need a simple configuration to get started, you can intercept any domain name and return any ip you need.

Running as a Service

npm install -g updns

Config

We configure routing in the way of hosts

You can use updns config command and then call vim quick edit, or find the module's installation directory and edit the config/hosts file

The service can be bound to an IP and port, such as for a specific ethernet adapter or any valid loopback address (127.0.0.42)

You can specify standard domains, or utilize regular expressions for dynamic matching

bind              0.0.0.0:53     # address => port (requires restarting the service)
proxy             8.8.8.8        # proxy => DNS Server
google.com        1.1.1.1        # domain => IP
/goo+gle\.com/    2.2.2.2        # regex: gooooooooooogle.com => IP

Start to use
