DnsPinSet

microsandbox_network::policy

Struct DnsPinSet 

Source 
pub struct DnsPinSet { /* private fields */ }
Expand description

Maps resolved IP addresses back to domain names.

Populated by the DNS interceptor when it resolves A/AAAA records. Used by the policy engine to match domain-based rules against destination IPs.

Implementations§

Source§

impl DnsPinSet

Source

pub fn new() -> Self

Source

pub fn lookup(&self, ip: IpAddr) -> Option<&HashSet<String>>

Returns the set of domains that resolved to ip, if any.

Source

pub fn remove_ip(&mut self, ip: &IpAddr)
