IP address validation for SSRF protection

Determines whether an IPv4 or IPv6 address is publicly routable. Private, loopback, link-local, carrier-grade NAT, documentation, benchmarking, multicast, reserved, IPv4-mapped IPv6, and other special-use destinations are handled conservatively.

Installation

dotnet add package Soenneker.Validators.IpAddresses.Ssrf

Usage

services.AddSsrfIpAddressValidatorAsSingleton();

ISsrfIpAddressValidator validator =
    serviceProvider.GetRequiredService<ISsrfIpAddressValidator>();

bool isPublic = validator.Validate("8.8.8.8");       // true
bool isPrivate = validator.Validate("192.168.1.10"); // false
bool isLoopback = validator.Validate(IPAddress.Loopback); // false

Validate(string) accepts unambiguous IP address literals only and performs no managed allocations. It does not resolve hostnames. Legacy abbreviated, octal, and hexadecimal IPv4 forms are rejected. For SSRF-safe HTTP requests, resolve every hostname and validate every returned address at connection time. Revalidate redirects as well, so DNS rebinding cannot bypass an earlier check.
