Asynchronous I/O Support¶
dns.asyncresolver modules offer
asynchronous APIs equivalent to those of
Dnspython presents a uniform API, but offers three different backend
implementations, to support the Trio, Curio, and asyncio libraries.
Dnspython attempts to detect which library is in use by using the
sniffio library if it is available. It’s also possible to
explicitly select a “backend” library, or to pass a backend to
a particular call, allowing for use in mixed library situations.
