hi Team,

we have configured AIR-AP2802I-D-K9 and added same access points in WLC .

configured SSID, interface and DHCP group, but ip not releasing.

Note: WLC controller available at different locations and access points available at different locations, we can view access points in WLC, but iP does not release.

what could be the issue

 - Have a checkup review of the mobility express controller configuration using these command(s) : https://community.cisco.com/t5/networking-knowledge-base/show-the-complete-configuration-without-breaks-pauses-on-cisco/ta-p/3115114#toc-hId-1039672820
          Feed the output into : https://cway.cisco.com/wireless-config-analyzer/

- What model of WLC?
- What version of software?
- What do you mean by "iP does not release"? 
DHCP leases expire automatically even if the client does not release the IP so it really shouldn't matter even if a client does not release the IP explicitly.

please find my response inline 

What model of WLC?--cisco 2500

What version of software? ---8.2.154.17

What do you mean by "iP does not release"? --

we placed the WLC controller one from Site A location and we added access points and IP also release.
but we added two other access points in a different location that is site B and added those two access points in the same WLC.
post we can see access points in WLC but ip is lease instead of site B segments rathan we get Site A segments.

I'm sorry but I still don't understand your explanation clearly.  I think you're saying site A/B clients are getting IPs from the other site?  If so then you probably have misconfiguration of your WLAN(s) or AP groups.  Check your config using:
https://cway.cisco.com/wireless-config-analyzer/
using "show run-config" output from the WLC (remember "config paging disable" before running that command).

8.2.154.17 is very old and long out of support, full of bugs.  Depending on your AP models you should be running at least 8.3.150.0 or 8.5.182.7 as per TAC recommended link below.  If your APs are all 2802 then upgrade to 8.5.182.7 (link below).  If you have other models of AP you can check the compatibility matrix below for supported software versions.
