As we everybody know.. Loop back address is
127.0.0.0 (Entire network address)
Here -
First Octate - 127
Second Octate - 0
Third Octate - 0
Forth Octate - 0
Convert those in binary - Using (128 64 32 16 8 4 2 1) code....
First Octate - 0 1 1 1 1 1 1 1
Second Octate - 0 0 0 0 0 0 0 0
Thirde Octate - 0 0 0 0 0 0 0 0
Fourth Octate - 0 0 0 0 0 0 0 0
So binary add of loopback address -
01111111 00000000 00000000 00000000
Note:
0 : Zero designate the corresponding decimal code value zero.
1 : One designate the corresponding decimal code value that
decimal number.

First of all 127.0.0.1 is the correct loopback address.
In binary that would be 01111111.00000000.00000000.00000001
(DEF)Loopback is a communication channel with only one endpoint. TCP/IP networks specify a loopback that allows client software to communicate with server software on the same computer. users can specify an IP address, usually 127.0.0.1, which will point back to the computer's TCP/IP network configuration. The range of addresses for loopback functionality is the range of 127.0.0.0 to 127.255.255.255. Similar to ping, loopback enables a user to test one's own network to ensure the IP stack is functioning properly.

Answer / jitendera kumar
no sahin it is not wrong it is correct but that value is
not given in to the option
so i marked it wrong
i think iot may be 7
explantion
scince loopback is 127.0.0.1
so in that frst bit is always off
remanig 7
thus aqll bit are on thus the nuric value of lopback
address might be 7
but but but i am not dam sure this time i am also confused
not little bit much more.so do not get it that it is wright
i am 30%sure that it migh be

How cud u say binary value of 1st octate, coz we know IP
address consist of four octate, each of 8 bits.
XXXXXXXX.XXXXXXXX.XXXXXXXX.XXXXXXXX
I don't think it wud be a justified answer if we say "7".
coz he is nt asking the binary bit of first octate. so we hv
to take or assume the conventional 4 octate criteria.
Hi.. Jitendera, this may open up some more question.
heheheheh..!!!!

Answer / jitendera kumar sinha
actualr sahin
my argue based on that consept
that is loop back address is 127.0.0.1
let consider its wild mask that is
0.255.255.255
that is match exct value of 1st octaet and three octet may
have value
try to ping 127.4.5.6
u will get reply through 127.0.0.1
ok that is 127 n/w bit is resved for the nic card
functionaly staus and we refred as it loop back address
now
scinselast three octet have any value then we are not aware
of that
scine first octet is fix for n/w id 127
then
from our most convanonal rule
128 64 32 16 8 4 2 1
0 1 1 1 1 1 1 1=127 that is 7 bit
scince that was in option so i mark it
i know u r corect but that option are not present in answer
sheet
and i am not bale to write that opton on answer sheet and
then mark
ha a ha haaaa
so i apply my wrong/wright consept and mark 7
i donot know it was wright or not so i placed it on all

Answer / nikhil maggu
OK got the same
0.0.0.0 is used for default routing
but can we use sumthing like "0.0.0.xxx", in any
parctice????????

Answer / jitu
han bhia nikhil
actualy if you use 0.0.0.xxx(1 to 255) then it will act as
wild mask bit
and you can use it
1 ospf routing protocol
2 access list
