Definition of Network Configuration

You’d better to take few minutes to watch the video of Network Configuration if you don't really understand the network setting that would be much more help to figure this hell issues before getting start!

Definition of Network Configuration

Internal IP - Located IP Address & Router

§    Check on your Mac IP Address – Media Access Control (Mac) Address has 12 digit number split by colon - E.g. 12:34:56:ab:cd:ef that is your physical Mac’s location

Click the Apple symbol on the left top corner -> select “About this Mac” -> “More Info” -> “System Report” -> “Network” -> “Location”  

§    Router IP – Local network router e.g. 192.168.2.1.

External IP – ISP (Internet Server Provider) Modem access to DNS (Domain Name Server).

§    DHCP (Dynamic Host Configuration Protocol) assign TCP/IP address (Transmission Control Protocol / Internet Protocol) to your Mac.

§    Connect to Web Server (Proxy Server) that the Client query and Server respond.

§    Https Server responds the security login pages request.

The reasons unable to access login page because the information source has been changed. The unknown source makes the server confusion.

Normally, you will get through on the Internet if you got the network ID (TCP/IP) that assign to your Mac / PC from DHCP Server.

Proxy server will respond to client requests and send the data of files and other resources as web pages. But the security login pages should ask for HTTPS server.

Connect to Network Config

System Preferences -> Network -> Advanced ->

Config “Wi-Fi “, “TCP/IP” and “DNS”, and then click “OK”.

  1  -  Wi-Fi – delete the unusual networks that would be confused your network connection.

  2  -  TCP/IP - What different between of IPv4 and IPv6?

          Mostly, we will use IPv4, click the “Renew DHCP lease” to request assign a new IP,      and then click “OK” -> “Apply”. (Please watch the other video tutorial of Solution of Login the HTTPs login page)

·     Network ID –

a). IPv4 = Internet Protocol version 4

It is 32 bits IP address that we use commonly. It can be 4 of 1 byte 8-11 decimal number separated by a dot as Class C id -192.168.8.1 / 10.3.4.5 / other 32 bits IP addresses.

It can support up to 2³² addresses, however they are finishing to be used in near future; every computer, cell phone, iPad, printer, machine and every device require IP address, so IPv6 is developed as a replacement.

b). The IP Subnet Mask on IPv4 –

The subnet mask 255.255.255.0 is 24 bits and consists of the network ID which are to be used for the host ID attempt to communicate with another system, identify different group IP addresses and many devices on the same local area network(LAN).

Router ID = usually we use Class C in 32-bit mask.

c). IPv6 = Internet Protocol version 6

The size increases extended to 128 bits, uses hexadecimal numbers that separated by colons as 1050:0:0:0:5:600:300c:326b

It can support up to 2¹²⁸ addresses with better security and network related features that will need multiple IP addresses or permanent connectivity, simplify mobile and router network.

d). Prefix Length 0f IPv6 –

The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4.

It is expressed as an integer between 1-128.

DNS – Domain Name Server

The DNS protocol is an important part of the web's infrastructure, serving as the Internet's phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.

**After done all the setting, click “Apply” to complete all the change requests.

The Real World Sample:

TCP/IP = Your personal ID

Trustful Certificate = Security Login Card or ID

Local IP = Your physical address
