TCP/IP အေၾကာင္းေလး ေျပာမယ္္ဗ်ာ

(၁) IP address ဆိုတာ ဘာလဲ ?


TCP/IP = Transmission Control Protocol and Internet Protocol ျဖစ္ပါတယ္ ။
IP တစ္ခု ဟာ 32 bit binary number ျဖစ္ၿပီး decimal ဂဏန္း 4 လံုးနဲ ့ေဖာ္ျပေလ ့ရွိပါတယ္ ။
decimal ဂဏန္း 1 လံုးစီဟာ 8 bits 0 to 255 (octets) ကုိကုိယ္စားျပဳပါတယ္ ။အဲလုိ ေဖာ္ျပတာကို “dotted decimal” လုိ ့ေခၚပါတယ္ ။
Example; 140.179.220.200 (Dotted decimal)
10001100.10110011.11011100.11001000 (Binary)

(၂) အမ်ိဳးအစား ဘယ္ႏွခု ရွိပါသလဲ ?


Classes အမ်ိဳးအစားကုိ အခုလို ခြဲထားပါတယ္ ။

Class Range of Address
A 1 to 126(127) binary 0xxx နဲ ့စ ပါတယ္။
B 128 to 191 binary 10xx နဲ ့စ ပါတယ္။
C 192 to 223 binary 110x နဲ ့စ ပါတယ္။
----------------------------------------------------------------------------
D 224 to 239 binary 1110 နဲ ့စ ပါတယ္။
E 240 to 254 binary 1111 နဲ ့စ ပါတယ္။

က်န္ေနတဲ့ 127(localhost) ကို local loopback အတြက္သံုးပါတယ္ ။သင္ 127.0.0.1 ကို ping ၿပီးစမ္းသပ္ႏိုင္ပါတယ္ ။
Class D addresses ကို multicasting အတြက္ သံုးပါတယ္။ Class E addresses ကုိေတာ့ future use ဆုိၿပီးသတ္မွတ္ထားပါတယ္ ။အဲဒါေၾကာင့္
သင့္ရဲ
့ IP address ကိုရိုက္တဲ့ အခါ 1 to 223 ကေနပဲ စရုိက္လို ့ရပါတယ္ ။ 224
ကေနစၿပီး ေနာက္ပုိင္းကုိ ရုိက္လုိ ့မရပါဘူး ။ အလြယ္တကူ စမ္းသပ္
ၾကည့္ႏုိင္ပါတယ္ ။

Private Network Address ၄ ခုရွိပါတယ္ ။


( Local loopback Address )- 127.0.0.1

( Class A )- 10.0.0.0
( Class B )- 172.16.0.0
( Class C )- 192.168.0.0

Class
ေတြကို ပံုမွန္အားျဖင့္ ဘယ္လုိဆံုးျဖတ္သလဲ ဆိုတာ ေလ့လာၾကရေအာင္- (N) က
network ကိုကိုယ္စားျပဳၿပီး (n) က node ကုိကိုယ္စားျပဳပါတယ္ ။
- Class A -- NNNNNNNN.nnnnnnnn.nnnnnnn.nnnnnnn
- Class B -- NNNNNNNN.NNNNNNNN.nnnnnnnn.nnnnnnnn
- Class C -- NNNNNNNN.NNNNNNNN.NNNNNNNN.nnnnnnnn
အဲဒါေၾကာင့္
Class A ကိုသံုးမယ္ဆိုရင္ network (N)ေပါင္း 2^8 = 255 ကိုသံုးႏုိင္မွာျဖစ္ၿပီး အဲဒီ network ရဲ ့ေအာက္မွာ ကြန္ပ်ဴတာေပါင္း (n)
255 x 255 x 255 =16581373 လံုးကိုတပ္ဆင္အသံုးျပဳႏုိင္မွာ ျဖစ္ပါတယ္ ။
Class
B ကိုသံုးမယ္ဆိုရင္ network (N)ေပါင္း 255 x 255 =65025
ကိုသံုးႏုိင္မွာျဖစ္ၿပီး အဲဒီ network ရဲ ့ေအာက္မွာ ကြန္ပ်ဴတာေပါင္း (n)
255 x 255 = 65025 လံုးကိုတပ္ဆင္အသံုးျပဳႏုိင္မွာ ျဖစ္ပါတယ္ ။
Class
C ကိုသံုးမယ္ဆိုရင္ network (N)ေပါင္း 255 x 255 x 255 =16581373
ကိုသံုးႏုိင္မွာျဖစ္ၿပီး အဲဒီ network ရဲ ့ေအာက္မွာ ကြန္ပ်ဴတာေပါင္း
(n)255 လံုးကိုတပ္ဆင္အသံုးျပဳႏုိင္မွာ ျဖစ္ပါတယ္ ။

(IP address မွာ
192.168. ေတြပဲ ဘာလုိ ့ျဖစ္ေနရတာလဲ လို ့မၾကာခဏ အေမးခံရပါတယ္။ကုိယ္သံုးမယ္
့ ကြန္ပ်ဴတာ အေရအတြက္(node)ဟာ ၂၅၅ လံုးကုိ မေက်ာ္ဘူး ဆိုရင္ Class C ကိုပဲ
သံုးၾကလို့ပါ။)
ေနာက္တစ္ခုကေတာ့ node မွာ decimal no: 0 နဲ ့ 255 ကိုထည့္လုိ ့မရပါဘူး။(ဥပမာ- 192.168.1.0* / 192.168.1.255* )
IP address မွာ node portion all Ones (11111111)=255 က Broadcast Address ျဖစ္ပါတယ္ ။
IP address မွာ node portion all Zeros(00000000)=0 က Network Address ျဖစ္ပါတယ္ ။

ရွင္ျပေပးတာေက်းဇူးတင္ပါတယ္
ေနာက္တစ္ခုကဒီ topic နဲ႔ ဆိုင္မဆိုင္ေတာ့မသိဘူးေနာ္ ေမးျခင္တာရွိလို႔ပါ..

IPV6 အေၾကာင္းေလးကို လည္းဆက္ၿပီးရွင္းျပေပးပါလား... သိျခင္လို႔ပါ... IPV6 နဲ႔ပတ္သတ္တာကုိ မသိလို႔ပါ..။

အစ္ကိုေရ IPV 4 / IPV 6 ကြာ ၿခားခ်က္ေလးေတြ လဲ ၇ွင္းၿပေပးပါအုန္း.......။။

Correct me if I am wrong. It is basically a 32 bit and 64 bit. IPv4 is 32 bit while IPv6 is 64 bit.

0.0.0.0 to 255.255.255.255 is 32 bit address.

So 64 bit address would be from 0.0.0.0 to 655xx.655xx.655xx.655xx (this one is what I think).

IPv6 is 128 bits addressing .

Address format is in 8 pairs of 16 bits hexadecimal numbers. Each pair include 4 Hex numbers, between 0000 to FFFF .

For example IPv6 address will be something like 234F:34FD:DFCA:124A:234F:34FD:DFCA:124A .

I think MoeZatKo once write about of IPv6 on MZ. Even though there is some misunderstanding ( i guess mis-translation) in detail parts of multicasting and broadcasting, it's a good basic one to read about of IPv6.

Bro xtrm,
Can you write some article about IPv6 (or) something related to your Field?

Bro Law Shay,
Can you also write some article about C++ (or) something related to your Field?

I know you two are geeks at your own field.
Can you contribute for M.I.T.R?

Thanks,

Thank you. I am nothing in networking. Very Happy
