NameserverResponse

A response from a remote nameserver

Functions

candidate_nameservers 🔒

Get the best nameservers by non-recursively looking them up for the domain and all its superdomains, in order. If no nameservers are found, the root hints are returned.

follow_cnames 🔒

Given a set of RRs and a domain name we’re looking for, follow CNAMEs in the response and return the final name (which is the name that will have the non-CNAME records associated with it).

get_better_ns_names 🔒

Given a set of RRs and a domain name we’re looking for, look for better matching NS RRs (by comparing the current match count). Returns the new matching superdomain and the nameserver hostnames.

get_ip 🔒

Given a set of RRs and a domain name we’re looking for, follow any CNAMEs in the response and get the address from the final A / AAAA record.

get_record 🔒

Given a set of RRs and a domain we’re looking for, return the record we’re looking for (if any).

resolve_combined_recursive 🔒

Helper function for resolving CNAMEs: resolve, and add some existing RRs to the ANSWER section of the result.

resolve_hostname_to_ip 🔒

Resolve a hostname into an IP address, optionally only doing local resolution.

resolve_recursive

Recursive DNS resolution.

resolve_recursive_notimeout 🔒

Timeout-less version of resolve_recursive.

resolve_with_nameserver_response 🔒

Helper function for answering a question given a response from an upstream nameserver: this will only do further querying if the response is a CNAME.

validate_nameserver_response 🔒

Validate a nameserver response against the question by only keeping valid RRs:
