What is the decimal representation of this IPv4 address 10010100.00101011.11001000.00001111?
You need to convert each of the four parts that are separated by dots, from binary to decimal. On Windows, the built-in calculator can help you with this. Just put it into scientific mode (on Windows XP) or programmer's mode (on Windows 7). Then, for each number, select binary mode, type in the number, and select decimal mode to convert to decimal.

Explain what the number 0 and the number 255 are used for in IPv4 addressing?
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.
What is the dotted decimal representation of the IPv4 address which is represented in binary string of 00001010.01100100.00010101.00000001?
Convert each binary number to decimal: Each digit to the left is worth twice what it is worth in the column to its right: each column starting from the right is worth 1, 2, 4, 8, 16, 32, ...; for an 8-bit number, the columns from the left are 128, 64, 32, 16, 8, 4, 2, 1; thus : 0000 1010 = 8 + 2 = 10 0110 0100 = 64 + 32 + 4 = 100 0001 0101 = 16 + 4 + 1 = 21 0000 0001 = 1 → 00001010.01100100.00010101.00000001 = 10.100.21.1 The IPv4 dotted decimal representation is just expressing the 32 bits of the address in the value of each of the 4 bytes used to store the 32 bits using decimal numbers with a dot between each byte's value so that it is not confused to be a single number, ie so that 10.100.21.1 is not read as 10100211 or 10,100,021,001 when the correct decimal value of the 32 bit binary number (0000 1010 0110 0100 0001 0101 0000 0001) is 174,331,137 (but converting that to binary is not as easy as converting an 8 bit (decimal number of range 0-255) to binary.
How many numbers are there in the world?
There is an infinite (infinite meaning there is no end) amount of numbers in the world! Suppose that you were to list all the numbers in the world in order, all I would have to do is add 1 to the largest number on that list to get a number that you have not included, but is in the world. However, until I wrote it down, it could be said to not exist in the world! For people who want to claim that there are only 10 "numbers", the digits 0-9, I have to point out that the world includes more than just the modern West and that in doing so they are excluding other number systems which are also in the world, even if not currently "in use" - engravings, etc can be found using them: For example the Greeks and Hebrews used their alphabets using the first 9 letters for 1-9, then the next 9 letters for 10-90, etc, Roman numerals are still used in some places and that uses 7 "digits" (I, V, X, L, C, D, M) - in all these cases numbers are written using multiple letters whole values are added together. And then there are other bases, for example hexadecimal is base 16 and uses the 16 digits 0-9, A-F. Technically time of a day is measured (in seconds since midnight) using sexagesimal, base 60, but to avoid the problems of finding 50 different symbols for the digits beyond 0-9, the digits are written using decimal but separated by a colon as opposed to just being written next to each other. (IPv4 internet addresses are actually a base 256 number with each digit written in decimal separated by a dot.) The Babylonians, who used the sexagesimal system, used blocks of combinations of two marks (a narrow and wide "wedge") to make up the 1-59 possible digits - did their system have 59 "Numbers" or just 2? They had no symbol for zero. The Mayan civilisation in Belize, Guatemala and southeastern Mexico used a vigesimal, base 20, system that used a combination of upto 4 dots and 4 lines (or iconographs of faces) to represent the decimal digits 1-19; the zero digit was represented by a separate shell symbol. So did the Mayans use 20 or 3 or 23 different "numbers"?
Expressed in dotted-decimal format the IPv4 address range is what?
0.0.0.0 to 255.255.255.255
How many address in IPv4 address?
32 bits in a IPv4 address
What is the difference between ipv4 and ip address?
IPV4 is a kind of IP Address.
How is an IPv4 address normally written?
The normal format is dotted decimal, where each octet is converted from binary to decimal and separated by a period, thus: 192.168.100.123
What type of address is ipv4 address?
The address space of IPV4 is limited to 4294967296 possible unique addresses.
How many bits are in TCP IPv4 ip address?
a TcP IPv4 ip address has 32 bits.
What is the size of today's standard (IPv4) IP address?
The size of an IPv4 address is 32 bits, or 4 bytes.
What defines an IPv4 logical network?
Hosts with the same network portion of their IPv4 address.
What is the difference between your IPv4 address and your IP address?
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.
What is 192 in 192.168.0.1IPA?
The 192 is the decimal representation of the first 8 bits of the IPv4 address given.In dot notation IPv4 addresses are given as four decimal numbers in the range 0-255 (each representing 8 bits of the 32 bits of the address) separated by dots.192.168 together provide the first 16 bits of a class C non-routeable private ip address - any addresses starting 192.168. are not routed across the internet but are intended for local nets; if access to the internet is required, they go via a gateway machine (with one NIC (Network Interface Card) on the local net and a second one on the internet) that provides Network Address Translation.
Which characteristic describes an IPv6 enhancement over IPv4?
IPv6 has a larger address space compared to IPv4, allowing for more unique addresses. This solves the issue of address exhaustion seen in IPv4.
What is the broadcast address on IPv4 networks?
The broadcast address on IPv4 networks is the subnet address, padded on the right with ones. For example, if the subnet address is 192.168.x.y, with a subnet mask of 255.255.0.0, then the broadcast address is 192.168.255.255.
