IPv4?

25

• TCP/IP Has Been Built On Version 4 Of The Internet Protocol IPv4 – Used Since 1981

• IPv4 Was Created When The Internet Was Just A Small Experimental Network.

• Considering Internet Growth & Change - Ipv4 Has Done Its Job Admirably.

• It Has Been Apparent For Many Years That Certain Limitations Of IPv4 Would Hold Back The Future Growth Of Both Internet Size And Services If Not Addressed.

About IPv4 - 1

26

• IPv4 Plays Key Role In Internet

• Replacing IPv4 Will Be A Major Endeavor

• The Necessary Changes Require Altering Nearly Everything In TCP/IP Operates.

• Replacing Ipv4 Is Necessary

• For Several Years, Development Of A New Version Of IP Has Been Underway,

– Officially Called Internet Protocol Version 6 (Ipv6)

– Also Called IP Next Generation Or Ipng

– IPv6 Is Poised To Take Over From Ipv4; It Will Be The Basis For The Internet Of The Future.

About IPv4 - IPv6

27

• Ipv6 Is Built Upon And Similar To Ipv4• IPv6 Performs The Same Functions As IPv4

– Addressing – Encapsulation – Fragmentation & Reassembly– Datagram Delivery & Routing

• Ipv6 Is Still Under Construction; It Continues To Change! – Changes Being Made To Both Ipv6 Standards And

Implementation Every Month

Use a pen to GENTLY press the reset button; hold it in until the wireless light goes off (usually about 5 seconds) and let go.

Access to the router should be password protected; this will • reset the password to adminThere are hundreds of possible configurations; this• resets the SSID to linksys;• resets the gateway to 192.168.1.1 ;• resets the router to issue DHCP addresses.

Windows 7 is awesome! It automatically connects to the new network! Your computer must be configured for DHCP!

In most networks, you will have to issue

ipconfig /releaseand ipconfig /renew to get a new ip address for the network!

Note that you can see that we have no Internet!

Does Changing The Router DHCP Range Automatically Change Your IP Address: Y/NReplace The Blue Screen Capture Below With Yours!

The Answer is __________

75

Changing The Router DHCP Range Did Not Automatically Change Your IP If You Restart Your Computer, It Would Acquire An IP Address In the Range

192.168.2.200 To 192.168.2.204

Changing The Router DHCP Range Did Not Automatically Change Your IP Address! If You Restart Your Computer, It Would Acquire An IP Address In the Range192.168.2.200 To 192.168.2.204

If You Were To Do IPCONFIG /RELEASE (To Release The Existing IP Address) andDo IPCONFIG /RELEASE (To Re-Acquire A New IP Address)

You Would Acquire An IP Address In the Range192.168.2.200 To 192.168.2.204

2. FTP Server to provide ftp services

3. HTTP Web Server to provide web services

4. Mail Server to provide mail services

5. Database Server to provide database services

117

Disable Router DHCP

Temporarily Disable The DHCP In Your Router (For The Moment!)


When You Disable DHCP, The Router Will No Longer Issue IP Addresses To Wireless Devices Or Cat 5 Ethernet Adapters Plugged Into The Router. This Does Not Prevent The Routing!

119

In Order To Route Traffic To One Specific Computer Behind The Firewall, We Must Always

Know The IP Of That Computer.
