Bump dnspython from 2.3.0 to 2.4.1

[dependabot]

Bumps dnspython from 2.3.0 to 2.4.1.

Changelog

Sourced from dnspython's changelog.

2.4.1

• Importing dns.dnssecalgs without the cryptography module installed no longer causes an ImportError.

• A number of timeout bugs with the asyncio backend have been fixed.

• DNS-over-QUIC for the asyncio backend now works for IPv6.

• Dnspython now enforces that the candidate DNSKEYs for DNSSEC signatures have protocol 3 and have the ZONE flag set. This is a standards compliance issue more than a security issue as the legitimate authority would have to have published the non-compliant keys as well as updated their DS record in order for the records to validate (the DS digest includes both flags and protocol). Dnspython will not make invalid keys by default, but does allow them to be created and used for testing purposes.

• Dependency specifications for optional features in the package metadata have been improved.

2.4.0

• Python 3.8 or newer is required.

• The stub resolver now uses instances of dns.nameserver.Nameserver to represent remote recursive resolvers, and can communicate using DNS over UDP/TCP, HTTPS, TLS, and QUIC. In additional to being able to specify an IPv4, IPv6, or HTTPS URL as a nameserver, instances of dns.nameserver.Nameserver are now permitted.

• The DNS-over-HTTPS bootstrap address no longer causes URL rewriting.

• DNS-over-HTTPS now only uses httpx; support for requests has been dropped. A source port may now be supplied when using httpx.

• DNSSEC zone signing with NSEC records is now supported. Thank you very much (again!) Jakob Schlyter!

• The resolver and async resolver now have the try_ddr() method, which will try to use Discovery of Designated Resolvers (DDR) to upgrade the connection from the stub resolver to the recursive server so that it uses DNS-over-HTTPS, DNS-over-TLS, or DNS-over-QUIC. This feature is currently experimental as the standard is still in draft stage.

• The resolver and async resolver now have the make_resolver_at() and resolve_at() functions, as a convenience for making queries to specific recursive servers.
