How many WEBPAGES are there on internet?


#1

Can anybody tell me with a reliable source that how many total web pages are there on internet and how many can be opened .. i.e. limit of new internet pages ..

with authenticated source....


#2

no one is really sure!

on a similar note google is indexing more than one trillion web pages


#3

no i read in a newspaper that internet has a capacity of 400 crores of webpages after that no new domain will be able to register is this true or right?

Oh yeah, we're very short of IPv4 addresses: http://arstechnica.com/news.ars/post/20080817-were-running-out-of-ipv4-addresses-time-for-ipv6-really.html

we are short of ipv4 addresses not domains!

and ISP are going to shift to ipv6 addresses when that happens so dont worry be happy

At the time of writing this message there are 247,567,345,698 web pages....oh wait a minute.....247,567,345,697 web pages on the internet because I just deleted one.

that is within itself a whole new topic, but at a glace

IPV4

IPV4 is 32 bits long (4 bytes). Address is composed of a network and a host portion, which depend on address class. Various address classes are defined: A, B, C, D, or E depending on initial few bits. The total number of IPv4 addresses is 4 294 967 296.

The text form of the IPv4 address is nnn.nnn.nnn.nnn, where 0<=nnn<=255, and each n is a decimal digit. Leading zeros may be omitted. Maximum number of print characters is 15, not counting a mask.

IPV6

28 bits long (16 bytes). Basic architecture is 64 bits for the network number and 64 bits for the host number. Often, the host portion of an IPv6 address (or part of it) will be a MAC address or other interface identifier.

Depending on the subnet prefix, IPv6 has a more complicated architecture than IPv4.

The number of IPv6 addresses is 10 28 (79 228 162 514 264 337 593 543 950 336) times larger than the number of IPv4 addresses.

The text form of the IPv6 address is xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx, where each x is a hexadecimal digit, representing 4 bits. Leading zeros may be omitted. The double colon ( : : ) may be used once in the text form of an address, to designate any number of 0 bits. For example, ::ffff:10.120.78.40 is an IPv6 IPv4-mapped address.
