BeauShort answer: four Longer answer: In binary form, as it is carried on the phyiscal network, an IPv4 address occupies four bytes. When I express an IP address such as 11.22.33.44, each of those numbers represents the value of one of these bytes. However, when an IPv4 address is stored as a string of decimal digits, such as the one I included above, it can take as much as 15 bytes (4 sets of 3 digits plus 3 periods) or even 16 bytes (many string implementations include a null terminator or a length byte).
IP version 4 (the current standard): 4 bytes.
IP version 6 (the proposed future standard, which will soon have to replace IPv4): 16 bytes.

IP version 6 (the proposed future standard, which will soon have to replace IPv4): 16 bytes.
An IPv4 address consists of four, 8 bit bytes (32 bits). These bytes are also known as octets.
For example, an IP address may look like this:
00001010 00000000 00000000 00000001
with 8 bits per segment/byte (the octet) and there are 4 segments.
An IP4 address consists of 32-bits and is also referred to as a dotted quad. For human readability the 32 bits are divided into 4 bytes of 8 bits each separated by a dot, but as far as the network is concerned the number is a single number consisting of 32 bits.

Which of the following IPv4 addresses is the loopback address?
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"
What is used to specify which bits of an ipv4 address are used for the network identifier and which bits are used for the host identifier?
Subnet Mask
How Many Classes in internet protocal address?
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
What is the range for experimental addresses?
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.
What is the difference between IP4 and IP6?
IPv6 is based on IPv4, it is an evolution of IPv4. So many things that we find with IPv6 are familiar to us. The main differences are:1.Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing.Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.2.Address extended to 128 bits. This allows for hierarchical structure of the address space and provides enough addresses for almost every 'grain of sand' on the earth. Important for security and new services/devices that will need multiple IP addresses and/or permanent connectivity.3.A lot of the new IPv6 functionality is built into ICMPv6 such as Neighbor Discovery, Autoconfiguration, Multicast Listener Discovery, Path MTU Discovery.4.Enhanced Security and QoS Features.Answer:IPv4 means Internet Protocol version 4, whereas IPv6 means Internet Protocol version 6.IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses. IPv4 can support up to 232 addresses, however the 32 bits IPv4 addresses are finishing to be used in near future, so IPv6 is developed as a replacement.IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features. Here are some examples of IPv6 address:1050:0:0:0:5:600:300c:326bff06::c30:0:0:0:0:0:192.1.56.10The most important difference is that it has a larger address space. IPv6 uses 128 bits, instead of the 32 bits used in an IPv4 address.There are also some changes in the header format, and some additional options, like built-in security options. These can be added to IPv4 through additional protocols, so this is really no big deal.IPv4 is like 10.36.05.2 while IPv6 is one huge garble.IPv4 is a 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses.

IPv4 uses 4 bytes; IPv6 uses 16 bytes for the address.Mainly, IPv6 has a larger addressing space; IPv6 addresses use 128 bits instead of 32 bits.
