Hello everybody! I am May Myat Hmu Khine who is working as a Web Developer
in SpiceworksMyanmar Co.Ltd. Today, I would like to share about Internet.


Research into packet switching started in the early 1960. Merit Network, NPL network and Telnet, were developed in the late 1960 and 1970 using a variety of protocols. These early years were documented in the 1972 Computer Networks. In 1982, the Internet Protocol Suite (TCP/IP) was standardized.

IP Address

TCP/IP Transmission Control Protocol and Internet Protocol

IP -32-bit binary number

decimal 4 digits, one decimal include 8 bits 0 to 255 (octets) (“dotted decimal”)

Eg – (Dotted decimal)

10001100.10110011.11011100.11001000 (Binary)

Class Range of Address

A 1 to 126(127) binary 0xxx

B 128 to 191 binary 10xx

C 192 to 223 binary 110x

D 224 to 239 binary 1110

E 240 to 254 binary 1111

(Local loopback Address) –

(Class A) –                          Machine Address (48 bits Physical Address)

(Class B) –                      Eg – 01-23-45-67-89-ab

(Class C) –

Class A – NNNNNNNN.nnnnnnnn. nnnnnnn. nnnnnnn                    255 x 255 x 255 =16581373

Class B – NNNNNNNN.NNNNNNNN. nnnnnnnn. nnnnnnnn              255 x 255 =65025

Class C – NNNNNNNN.NNNNNNNN. NNNNNNNN.nnnnnnnn           255

Most Use IP address

192.168. *.*

Eg.* /*

IP address – node portion all Ones (11111111) = 255 (Broadcast Address

IP address – node portion all Zeros (00000000) = 0 (Network Address)

IP6       255×255×255×255×255×255 = 274,941,996,890,625

Type of Internet/Network


ADSL offers speeds of up to 8Mbps downstream and 448Kbps upstream 1Mbps.

ADSL2 offers speeds of up to 12Mbps downstream and 448Kbps upstream 1Mbps.

ADSL2+ offers speeds of up to 24Mbps downstream and 448Kbps upstream 1Mbps.


SDSL is called symmetric because it supports the same data rates for upstream and downstream traffic.

A similar technology that supports different data rates for upstream and downstream data is called asymmetric digital subscriber line (ADSL).

Internet service Provider (ISP)

An Internet service provider (ISP) is an organization that provides services for accessing and using the Internet.

Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.

Internet services typically provided by ISPs include Internet access, Internet transit, domain name registration, web hosting, Usenet service, and colocation.

Internet Error Code

404 – Bad Request

(eg –

404 – Not Found

eg – removed page, password wrong, block web address

403 – For Hidden

eg – required password, Isp (block)

401 – Unauthorized

(e.g –, ( – required password

503 – Service Unavailable

e.g – – spam, Spyware, server down

Malware Proxy server is refusing

e.g – Ip address false, Proxy server block (proxy IP – “”)

I hope you will enjoy to read this post and next time I will share more interesting post.
