Cisco IOS Version 12.0(9)

[bbutler3295]

OK i have found out from previous posts that this version of Cisco IOS does not support dynamicly assigned IP's, so i will not be able to use this IOS to support my ISP, my router type is cisco 1605. My question is what version will support dynamicly assigned ip's, and where can i purchase a copy, what are my options, do i have to go directly to cisco.

Thanks in advance.

Yes, this feature will need to be purchased in your IOS version and can be purchased directly from Cisco or your reseller.

If you're talking about IP addresses dynamically assigned to an ethernet interface, then it's a feature called DHCP (dynamic host configuration protocol).

This link describes it in detail:

You will need IOS release 12.1(2)T or later or any 12.2 release.
