gdns : Tools to work with the Google DNS over HTTPS API
Traditional DNS queries and responses are sent over UDP or TCP without encryption. This is vulnerable to eavesdropping and spoofing (including DNS-based Internet filtering). Responses from recursive resolvers to clients are the most vulnerable to undesired or malicious changes, while communications between recursive resolvers and authoritative nameservers often incorporate additional protection.
To address this problem, Google Public DNS offers DNS resolution over an encrypted HTTPS connection. DNS-over-HTTPS greatly enhances privacy and security between a client and a recursive resolver, and complements DNSSEC to provide end-to-end authenticated DNS lookups.
More info at https://developers.google.com/speed/public-dns/docs/dns-over-https.
The following functions are implemented:
bulk_query: Vectorized query, returning only answers in a data framehas_spf: Test for whether a DNS TXT record is an SPF recordis_hard_fail: SPF “all” type testis_soft_fail: SPF “all” type testpasses_all: SPF “all” type testquery: Perform DNS over HTTPS queries using Googlespf_exists: SPF field extraction functionsspf_includes: SPF field extraction functionsspf_ipv4s: SPF field extraction functionsspf_ipv6s: SPF field extraction functionsspf_ptrs: SPF field extraction functionssplit_spf: Split out all SPF records in a domain’s TXT record
