Why some ISPs allocates their users with static IP addresses even if they have the option to allocate IP addresses dynamically via DHCP.
As most of the users don't need the static IP addresses( as they don't want their computer to be used as a server ) then what is benifit on part of the ISP to dedicate an IP address to a single user even if that user is not connected to the internet. Is this not the wastage of their IP address pool ?

you would want a static ip address if you use something like remote desktop or if you got a web server or something else that is easier to use the same ip address. it costs extra though
 
When NOT to use a Static IP Addresses

1. If you browse the Internet.
2. If you send and receive e-mail via an offsite server (the normal method).
3. If you download or upload files.
4. If you use Instant message services or chat services.

When to use a Static IP Addresses

You need one or more Static IP addresses if any of the following are true:

1. You run one or more Web server's directly on your site that require external access (from the Internet, or Extranet but not typically an Intranet) .
2. You run one or more E-mail server's directly on your site that require external access (from the Internet, or Extranet but not typically an Intranet) .
3. You run one or more FTP server's directly on your site that require external access (from the Internet, or Extranet but not typically an Intranet) .
4. You run any other service or 'Application' that requires external access (from the Internet or an Extranet). Some Financial Terminal Client applications require that you have a static IP address for licensing purposes.
5. You allow 'incoming' Video Conferencing you may need to use static IP addresses.

DHCP is no magical bullet for increasing IP pool. If broadbands advertise themselves as always-on there must be a reservation of available IP in case the modem is actually on.

Given that need, DHCP is unnecessary complexity. But there is no statement saying that they can't manage IP in anyway including changing its IP; except those business account. But having residential IPs entered manually has long gone.

Dial ups function Point-to-Point so all these discussion is N/A moot.
