ISPs with internal network IP ranges

[Mega Member]

hi,
if the internal network ip range use by the ISP for providing service then how is that possible to change ip? i have router with ip 192.168.XXX.XXX,so my question can i assign IP range to 10.0.0.0 – 10.255.255.255. which use by ISP.


I mean this range :
10.65.0.0 – 10.0.255.255
172.31.154.0 – 172.31.154.255
192.168.0.0 – 192.168.255.255

There is another range of IP addresses that don't appear on the Internet and are reserved for private networks:-

169.254.0.0 to 169.254.255.255.

This is called the APIPA range (Ah-peep-ah) - Automatic Private IP Addressing.

Microsoft has incorporated this into all recent versions of Windows.

The theory is that if a workstation has been set to get its IP parameters using DHCP but no DHCP server responds to the workstation's broadcast then, using the principle that any IP address is better than none, the workstation picks an IP address for itself, at random, from the APIPA range. The workstation may then be able to communicate with other workstations in a similar situation but it almost certainly won't be able to access any server resources or the Internet.

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

We will refer to the first block as "24-bit block", the second as "20-bit block", and the third as "16-bit" block". Note that the first block is nothing but a single class A network number, while the second block is a set of 16 continuous class B network numbers, and the third block is a set of 255 continuous class C network numbers.

hi,
I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
