URL-Binary Number

[justravee]

How do i convert a URL into a binary number which will enable me to access that website?

I know that by pinging a particular website we get the IP address of same but don't know from then on how to proceed ahead.

When i ping a site i get a request time out reply ie. zero packet received.

Do you mean you want to convert a text url like this

www.computerhope.com

into an ip address like this

81.200.64.50

?

Firstly the ip address is not a "binary number". It is four decimal numbers separated by dots, a so-called "dotted quad".

batch code

getIP.bat

Code: [Select]

@echo off
for /f "tokens=1-26 delims=[]" %%A in ( ' ping %1' ^| find "Pinging" ' ) do set IPaddress=%%B
echo IP address is %IPaddress%

use like this

Code: [Select]

C:\>getIP.bat www.computerhope.com
IP address is 81.200.64.50

How can we access a website by a binary no. ?

what u need to do is convert the ip decimal (either the first two nos. or last two separated by decimal) into binary no. and then paste the binary no. to the address n access .....i mean this is what i did 5 years back...but i dont remember now......

This is useful when u wanna access any site under the sun.....

If u know let me know

I very much doubt it, but if he wants binary I'll damned well give him binary!

Getip2.bat

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set binIP=
for /f "tokens=1-2 delims=[]" %%A in ( ' ping %1' ^| find "Pinging" ' ) do set IPaddress=%%B
for /f "tokens=1-4 delims=." %%B in ("%IPaddress%") do (
    call :decbin %%B
    set binIP=!bstring!
    call :decbin %%C

    )

goto end

  SET /A a=%1
  SET /A b= (%a% "&" 128)

echo Decimal IP address is %IPaddress%
echo  Binary IP address is %BinIP%

Code: [Select]

C:\>getip2 www.computerhope.com
Decimal IP address is 81.200.64.50
 Binary IP address is 01010001.11001000.01000000.00110010
justravee, type that binary IP address into your browser and tell us what happens...

this is what i did 5 years back...but i dont remember now

Don't you just love this type of question?

[patio]

I for one can't fathom the dilemna...
I thought your answers solved the issue...

Perhaps i'm wrong but it works  on my end...

Uh ..., is binary really supposed to work?  I get: Firefox can't find the server at 01010001.11001000.01000000.00110010

shhhh! Don't spoil the surprise!

More compact decimal to binary conversion

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set binIP=
for /f "tokens=1-2 delims=[]" %%A in ( ' ping %1' ^| find "Pinging" ' ) do set IPaddress=%%B
for /f "tokens=1-4 delims=." %%B in ("%IPaddress%") do (
    call :decbin %%B
    set binIP=!bstring!
    call :decbin %%C
    set binIP=!binIP!.!bstring!
    call :decbin %%D
    set binIP=!binIP!.!bstring!
    call :decbin %%E
    set binIP=!binIP!.!bstring!
    )

goto end

:decbin
set /a a=%1
set bstring=
FOR %%V IN (128 64 32 16 8 4 2 1) do (
      SET /A b=%a% "&" %%V
      if !b! EQU 0 (set bstring=!bstring!0) else (set bstring=!bstring!1)
    )
goto :eof
       
:end
echo Decimal IP address is %IPaddress%
echo  Binary IP address is %BinIP%

a normal person doing normal routine task doesn't need to input binary numbers to url to surf a site. I can't think of a reason one wants to do this, except, 1) its homework, 2) you are trying to bypass the security system.

I believe the entire point Salmon trout is making is that they are NOT binary numbers, they are Decimal- that is, base-10, numbers.

You can't surf to a website by entering an ip address as a sequence of binary strings separated by dots. It doesn't work. The OP asked about converting a url into a "binary" number and was told that dotted quads use decimal numbers. He ignored this, asking more or less the same question again. Out of whimsy I concocted a script to translate a web address into binary strings as well as decimal, to prove that it doesn't work.

The only reason I can think for wanting IP addresses for websites is to bypass DNS or HOSTS restrictions on surfing, also as you say, homework.
