Why is this so?..I have no clue as I don’t work for WC
For normal users, the change is transparent and usual browsing/downloading will work as before with no apparent change.
Having a public IP is better for torrents etc. and for advance users needing port forwarding to enable remote access to their computers from internet.
Hope this explains
Wateen WiMAX used to have this problem of “one IP for all” - where more than one user used the same public IP address. This caused problems with rapidshare (which would report “your IP address is already downloading a file”. As well as with torrent software like utorrent - which benefit if you can open a port for incoming connections.
Availability of a public IP address is a REQUIREMENT of a standard “internet connection”. If you don’t have that (and are doing “one IP for all” that is essentially a crippled “internet” connection). It only allows usage of some very limited services (like one way - initiated by you - web browsing etc.). While this is sufficient for most users, it should be clear that ALLOWING this practice to continue is a disservice to the development of full service internet in Pakistan. Some of these typical users may later find that they cannot use the internet in a way that is being used all over the world - except Pakistan.
So we NEED a standard internet connection - and for users to understand it’s value (even though they themselves may not use it).
That someone was NOT able to connect to their video in-house website etc. is a TRIVIAL matter - easily resolvable by the company - since they control who gets access and who doesn’t. They will just allow that block of public IP addresses (that are now being assigned instead of the dummy ones) access as well.
Hope this clarifies this.
Just as background:
Similarly if you want to run an FTP server (or an HTTP server) you HAVE to open a port so outside users can initiate a connection to a program running on your computer.
Since most routers/modems also have a “router” builtin which blocks most ports (similar to what firewall software ALSO does like “zonealarm” or windows builtin “windows defender”), plus most also do NAT (Network Address Translation) where ONE IP address is shared among computers on your home LAN. Computers on this LAN are therefore assigned dummy IP addresses like “192.168.1.x” or “10.0.0.x” (which are standard “dummy addresses” for such use).
To therefore enable FTP servers to run on one machine on your local LAN, you have to tell the router/modem to forward incoming connections to port X to computer on local LAN with IP address 192.168.1.YYY or something. This is called “port forwarding”.
