IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.
Navigate to your Ethernet card settings, IPV4 and choose manual for your DNS server and use Googles free DNS servers: Primary: 8.8.8.8 Secondary: 8.8.4.4
IPv4 1) Header (20-60 bytes). 2) Routed Protocol. 3) Types of address: i) Unicast ii) Multicast iii) Broadcast (limited/Direct) 4) 32-bit address. 5) Address space is 2^32. 6) Format of address : Decimal dotted. 7) IPsecurity support is optional. IPv6 1) Header is fixed (20 bytes). 2) ICMP6, IP 3) Types of address: i) Unicast ii) Multicast iii) Anycast 4) 128-bit address. 5) Address space is 2^128. 6) Format of address : colon hex notation. 7) IPsecurity support is built in.

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 default gateway on host A is incorrectly configured.

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.
When tunneling IPv6 over IPv4, the overhead primarily consists of the additional IPv4 header and any encapsulation overhead. An IPv4 header is typically 20 bytes, while an IPv6 header is 40 bytes. Thus, the total overhead for tunneling one IPv6 packet over IPv4 would be 20 bytes, resulting in a total packet size increase of 20 bytes for every IPv6 packet transmitted. This additional overhead may impact performance, especially in networks with high traffic or limited bandwidth.

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"
