Struct IPv4NodeID 

pub struct IPv4NodeID {
    pub node_id: Vec<u8>,
    pub ipv4_addr: Ipv4Addr,
    pub public_key: Vec<u8>,
    pub signature: Vec<u8>,
    pub timestamp_secs: u64,
    pub salt: Vec<u8>,
}

IPv4-based node identity that binds node ID to actual network location Mirrors IPv6NodeID for security parity on IPv4 networks

Fields

node_id: Vec<u8>

Derived node ID (SHA256 of ipv4_addr + public_key + salt + timestamp)

ipv4_addr: Ipv4Addr

IPv4 address this node ID is bound to

public_key: Vec<u8>

ML-DSA public key for signatures

signature: Vec<u8>

Signature proving ownership of the IPv4 address and keys

timestamp_secs: u64

Timestamp when this ID was generated (seconds since epoch)

salt: Vec<u8>

Salt used in node ID generation (for freshness)

Implementations

impl IPv4NodeID

pub fn generate( ipv4_addr: Ipv4Addr, secret: &MlDsaSecretKey, public: &MlDsaPublicKey, ) -> Result<Self>

Generate a new IPv4-based node ID

Delegates to GenericIpNodeID for the core generation logic.

pub fn verify(&self) -> Result<bool>

Verify that this node ID is valid and properly signed

pub fn extract_subnet_24(&self) -> Ipv4Addr

Extract /24 subnet from IPv4 address (Class C / most ISP allocations)

pub fn extract_subnet_16(&self) -> Ipv4Addr

Extract /16 subnet from IPv4 address (Class B / large ISP allocations)

pub fn extract_subnet_8(&self) -> Ipv4Addr

Extract /8 subnet from IPv4 address (Class A / regional allocations)

pub fn age_secs(&self) -> u64

Get the age of this node ID in seconds

pub fn is_expired(&self, max_age: Duration) -> bool

Check if the node ID has expired (older than max_age)
