IPv4 basic characteristics: Connectionless - No connection is established before sending data packets. Best Effort (unreliable) - No overhead is used to guarantee packet delivery. Media Independent - Operates independently of the medium carrying the data.

The header of an IP packet does not include fields required for reliable data delivery. There are no acknowledgments of packet delivery. There is no error control for data.

You can use this to try and parse it: IPAddress.TryParse Then check AddressFamily which Returns System.Net.Sockets.AddressFamily.InterNetwork for IPv4 or System.Net.Sockets.AddressFamily.InterNetworkV6 for IPv6. EDIT: some sample code. change as desired: string input = "your IP address goes here"; IPAddress address; if (IPAddress.TryParse(input, out address)) { switch (address.AddressFamily) { case System.Net.Sockets.AddressFamily.InterNetwork: // we have IPv4 break; case System.Net.Sockets.AddressFamily.InterNetworkV6: // we have IPv6 break; default: // umm... yeah... I'm going to need to take your red packet and... break; } }
The minimum size of an ICMP packet is 8 bytes, which includes the 8-byte ICMP header without any additional data. The maximum size of an ICMP packet is 65,535 bytes, which includes the maximum payload that can be carried within an IPv4 packet.
127.0.0.1 is the loopback address in IP.... or in the (slightly modified) words of Dorthy Gale when she returned from Oz "There's no place like 127.0.0.1"
The maximum permissible size for an IPv4 packet is 65,535 bytes, which includes both the header and the data payload. Since the maximum size of the header is 60 bytes, this allows for a maximum data payload of 65,475 bytes. However, in practical use, the Maximum Transmission Unit (MTU) often limits the size of packets on networks, typically to 1,500 bytes for Ethernet.
