show devices info on Cisco Switch

Using sh arp in Cisco Switch, it lists out the following. Why does IP 10.50.10.2 get several different MAC addresses ? This IP has been reserved in DHCP and it shouldn't lease to the clients

10.50.10.2      34bb.1f59.70f1      Vlan3
10.50.10.2      285a.ebee.8c67      Vlan3
10.50.10.2      f01f.af1c.fcee       Vlan3
10.50.10.2      bc85.56bc.01c3      Vlan3
10.50.10.2      e82a.eadd.6d8c      Vlan3
10.50.10.2      5440.ade7.1180      Vlan3
10.50.10.2      5c26.0a80.bafb      Vlan3
10.50.10.2      bc85.56bc.01c4      Vlan3
10.50.10.2      f01f.af1c.fc3a       Vlan3

Using sh mac-address-table, a port display several MAC addresses as well. Under what condition should the output appear like this ?

cc29.f5bd.c660 DYNAMIC Gi1/0/2
cc3a.6184.2d0e DYNAMIC Gi1/0/2
cc3d.82bd.b14f DYNAMIC Gi1/0/2
cc3d.82bf.f1f8 DYNAMIC Gi1/0/2
cc3d.82bf.f1fd DYNAMIC Gi1/0/2

This is typical for trunks. or ports where you have switch attached even as access port. Many devices are accessible through Gi1/02 port.
