Configuration for IP diversity enforcement at multiple subnet levels

Fields

max_nodes_per_64: usize

Maximum nodes per /64 subnet (default: 1)

max_nodes_per_48: usize

Maximum nodes per /48 allocation (default: 3)

max_nodes_per_32: usize

Maximum nodes per /32 region (default: 10)

max_nodes_per_ipv4_32: usize

Maximum nodes per single IPv4 address (/32) - dynamic by default

max_nodes_per_ipv4_24: usize

Maximum nodes per /24 subnet (Class C) - default: 3x per-IP

max_nodes_per_ipv4_16: usize

Maximum nodes per /16 subnet (Class B) - default: 10x per-IP

max_per_ip_cap: usize

Absolute maximum nodes allowed per single IP (default: 50)

max_network_fraction: f64

Maximum fraction of network any single IP can represent (default: 0.005 = 0.5%)

max_nodes_per_asn: usize

Maximum nodes per AS number (default: 20)

enable_geolocation_check: bool

Enable GeoIP-based diversity checks

min_geographic_diversity: usize

Minimum number of different countries required

Implementations

impl IPDiversityConfig

pub fn testnet() -> Self

Create a testnet configuration with relaxed diversity requirements.

This is useful for testing environments like Digital Ocean where all nodes share the same ASN (AS14061). The relaxed limits allow many nodes from the same provider while still maintaining some diversity tracking.

Warning

This configuration should NEVER be used in production as it significantly weakens Sybil attack protection.

pub fn permissive() -> Self

Create a permissive configuration that effectively disables diversity checks.

This is useful for local development and unit testing where all nodes run on localhost or the same machine.

pub fn is_relaxed(&self) -> bool

Check if this is a testnet or permissive configuration.
