DNS Server

A DNS Server implemented by Python with powerful lib dnslib.

Not a DNS proxy!

Typically it's a homework from SUSTech CS305 Computer Networking. Thought it was easy but it turned out that it's far more complicated than any other homework I had in this course.

Features

• With FLAG_TS_ITER set to True, NS records can be also parsed into IP address, which is exactly what a real DNS server should do.

• CNAME answers are automatically attached with A type IP.
