* Note: On AIX, it is frequently necessary to use an IPv6 address for ping6. If a hostname with A and AAAA records is used, AIX will try to ping6 its IPv4 address.

* X = hostname or IPv6 address. If using a hostname with both A and AAAA records, you must include the "( Addrtype ipv6" modifier. Otherwise, this modifier is optional. Note: there is no closing ")".

AIX 5.3

 

 

 

 

ISC 4.1

 

dhclient -6 -r

 

dhclient -6 XX; stateless: dhclient -6 -S XX; prefix delegation: dhclient -6 -P XX; temporary: dhclient -6 -T XX

WIDE DHCPv6

 

dhcp6ctl -C stop interface XX

 

dhcp6s XX, if the client isn't running. Or, dhcp6ctl -C start interface XX

Windows Vista/7

ipconfig /all

"XX" denotes the interface name, e.g., eth0 or e1000g0.

1. To return the lease to the DHCPv6 server, use "release." Alternatively, to deconfigure the address from the interface, and journal it to disk for later use, use "drop".
