Struct mxdns::MxDns

pub struct MxDns { /* private fields */ }

Utilities for looking up IP addresses on blocklists and doing reverse DNS

Implementations

impl MxDns

pub fn new<S>(blocklists_fqdn: S) -> Result<Self>

where S: IntoIterator, S::Item: Into<String>,

Create a MxDns using the system provided nameserver config

pub fn with_dns<I, S>(bootstrap_dns: I, blocklists_fqdn: S) -> Self

where I: Into<IpAddr>, S: IntoIterator, S::Item: Into<String>,

Create a MxDns that uses the given DNS server for standard queries.

pub fn on_blocklists<A>(&self, addr: A) -> Vec<Result<bool>>

where A: Into<IpAddr>,

Queries blocklists for the given address Returns a vector where each entry indicates if the address is on the blocklist

pub fn is_blocked<A>(&self, addr: A) -> Result<bool>

where A: Into<IpAddr>,

Returns true if the address is on any of the blocklists

pub fn reverse_dns<A>(&self, ip: A) -> Result<Option<String>>

where A: Into<IpAddr>,

Does a reverse DNS lookup on the given ip address Returns Ok(None) if no reverse DNS entry exists.

pub fn fcrdns<A>(&self, ip: A) -> Result<FCrDNS>

where A: Into<IpAddr>,

Does a Forward Confirmed Reverse DNS check on the given ip address This checks that the reverse lookup on the ip address gives a domain name that will resolve to the original ip address. Returns the confirmed reverse DNS domain name.

Trait Implementations

impl Clone for MxDns

fn clone(&self) -> MxDns

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
