MyIpAddress 2.0.0

MyIpAddress is an advanced .NET utility library for IP/network management and validation tasks.

Version 2.0.0 is fully backward compatible with version 1.0 and adds a range of advanced features for modern .NET projects while still supporting legacy .NET Framework (4.5+).

🆚 Version Comparison: 1.0 vs 2.0

Feature Version 1.0 Version 2.0
Validate IPv4 ✅ ✅
Get local IPv4 address ✅ ✅
Access control via IP whitelist/blacklist ✅ ✅ (ASP.NET Core only, legacy safe)
Validate IPv6 ❌ ✅
Get local IPv6 address ❌ ✅
Get public IP ❌ ✅
Reverse DNS lookup ❌ ✅
Check IP in CIDR range ❌ ✅
Ping host connectivity ❌ ✅
Get MAC addresses of local network interfaces ❌ ✅
Calculate subnet mask from CIDR ❌ ✅
Hostname validation ❌ ✅
Email validation ❌ ✅
Multi-target support (.NET 4.5+, .NET 6/7) ❌ ✅
Backward compatibility with v1.0 N/A ✅

📦 Installation

Install-Package MyIpAddress -Version 2.0.0
Supports:

.NET Framework 4.5+

.NET 6.0

.NET 7.0

⚡ Features
IPv4 & IPv6 validation

Get local IPv4 & IPv6 addresses

Retrieve public IP

Reverse DNS lookup

Check if an IP is in a CIDR range

Ping host connectivity

Get MAC addresses of local network interfaces

Calculate subnet mask from CIDR

Validate hostnames and email addresses

Access control via whitelist/blacklist (ASP.NET Core)

Fully backward compatible with version 1.0

🛠 Example Usage
csharp
Copy code
using MyIpAddress;

// Legacy .NET Framework
var helper = new IpAddressHelper();

// ASP.NET Core
// var helper = new IpAddressHelper(httpContextAccessor, configuration);

// Validate IPv4 & IPv6
bool isValid = helper.IsValidIpAddress("192.168.0.1");
bool isValidIPv6 = helper.IsValidIpAddress("2001:0db8:85a3::8a2e:0370:7334");

// Get local IPs
string localIPv4 = helper.GetLocalIPv4Address();
string localIPv6 = helper.GetLocalIPv6Address();

// Get public IP
string publicIP = await helper.GetPublicIpAsync();

// Check CIDR range
bool inRange = helper.IsIpInRange("192.168.0.10", "192.168.0.0/24");

// Ping a host
bool canPing = helper.PingHost("google.com");

// Retrieve MAC addresses
string[] macs = helper.GetLocalMacAddresses();

// Subnet mask from CIDR
string subnet = helper.GetSubnetMask(24);

// Hostname & Email validation
bool isValidHost = helper.IsValidHostName("example.com");
bool isValidEmail = helper.IsValidEmail("test@example.com");

// Reverse DNS
string hostName = helper.ReverseDnsLookup("8.8.8.8");
🔧 Notes
ASP.NET Core dependency (IHttpContextAccessor & IConfiguration) is only used for IsAccessGranted.

All other methods are fully compatible with legacy .NET Framework.

Version 2.0 is safe to upgrade for any projects using version 1.0 without breaking changes.
