In IPv4, which uses 4x bytes or 32 bits, there is a theoretical maximum of 4,294,967,296 IP addresses. In IPv6, which attempts to resolve the address shortage, uses 128bits, giving a maximum of ~ 340,282,366,920,938,463,463,374,607,431,770,000,000 addresses.
In C there are four storage classes: automatic, external, register and static.
IPv6 is not a separate Internet. It is a separate type of address. Machines can have both IPv4 and IPv6 addresses simultaneously. Many web servers already do this, and nearly all of the Internet's backbone routers have both types of address. Theoretically, if you are using IPv4 or IPv6, your data will take the same path, across the same hardware, to its destination. However, you may not be able to get an IPv6 address from your Internet Service Provider, perhaps since they are not yet IPv6-ready (often the case with smaller ISPs). In this case, you can setup a 6-to-4 tunnel which connects your IPv6 network inside your home to the IPv4 network of your ISP. Presumably, that ISP will also have a 4-to-6 tunnel allowing your packets to make their way to the IPv6 destination. That being said, if you know the IPv4 address of the same server, you can just use that without the need for IPv6. Only in the rare cases where servers only have an IPv6 address do you need to ensure that your packets come from an IPv6 address, then travel to the destination somehow (directly across an IPv6 network, or using tunnels as described above).
In java 1.1 version 250 classes are there java 1.2 version 500 classes are there i don't about other versions. but i want to know other version classes also. please post any body known these other version classes list....

IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.

The address space of IPV4 is limited to 4294967296 possible unique addresses.
192.169.32.1
One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.

IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
When applying IPv4 addresses to router interfaces on a network, you would manually configure predictable addresses. For example, the lowest or highest address of the local subnet, on each particular router interface.
Number 0 is used at the end of an IPv4 address for network identifiers and number 255 is used at end of an IPv4 for broadcast addresses.
IP addresses are of two types IPV4 and IPV6 . Depending upon the version the length of IP address differs . IPV4 is 32 bit long and IPV6 is 128 bits long.
