General Commands

OS	Display IPv6 routing table	ping6	traceroute6	Display IPv6 Addresses	Display IPv6 connections	Flush DNS cache
Mac OS X	`netstat -rnf inet6`	`ping6`	`traceroute6`	`ifconfig -a inet6`	`netstat -f inet6`	10.3, 10.4: `lookupd -flushcache` 10.5: `dscacheutil -flushcache`
Solaris	`netstat -rnf inet6`	`ping -A inet6`	`traceroute -A inet6`	`ifconfig -a6`	`netstat -f inet6`	8, 9: `/etc/init.d/nscd stop && /etc/init.d/nscd start` 10: `svcadm restart name-service-cache`
Linux	`netstat -rnA inet6`	`ping6`	`traceroute6`	`ip -6 address show`	`netstat -A inet6` / `netstat --inet6`	`/etc/rc.d/init.d/nscd restart`
AIX	`netstat -rnf inet6`	`ping -a inet6`*		`ifconfig -a inet6`
FreeBSD	`netstat -rnf inet6`	`ping6`	`traceroute6`	`ifconfig -a inet6`	`netstat -f inet6`	`/etc/rc.d/named restart`
Windows	`netstat -rn` or `netsh interface ipv6 show routes`	`ping -6`	`tracert -6`	`ipconfig`	`netstat -p IPv6`	`ipconfig /flushdns`
z/OS (TSO)	`NETSTAT ROUTE ADDRTYPE IPV6`	`PING X ( Addrtype ipv6`	`TRACERTE X ( Addrtype ipv6`		`NETSTAT SOCKETS`
z/OS (Unix)	`netstat -r ADDRTYPE IPV6`	`ping -A ipv6 X`	`traceroute -A ipv6 X`		`netstat -s`
Vyata	`show ipv6 route`	`ping6`	`traceroute6`

* 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 ")".

Neighbor Discovery Cache commands

OS	Display neighbor cache	Delete one entry	Flush neighbor cache
Mac OS X	`ndp -a`	`ndp -d`	`ndp -c`
Solaris	`netstat -pf inet6`
Linux	`ip -6 neigh show`		`ip -6 neigh flush`
AIX	`ndp -a`	`ndp -d`
FreeBSD	`ndp -a`	`ndp -d`	`ndp -c`
Windows	`netsh interface ipv6 show neighbors`		`netsh interface ipv6 delete neighbors`
IOS	`show ipv6 neighbors`		`clear ipv6 neighbors`
JunOS	`show ipv6 neighbors`		`clear ipv6 neighbors`
z/OS (TSO)	`NETSTAT ND`
z/OS (Unix)	`netstat -n`
Vyatta	`show ipv6 neighbors`		`clear ipv6 neighbors`

Miscellaneous

OS	Show stateless-autoconfig address lifetime	Show multicast group membership
Mac OS X	`ifconfig -L`	`netstat -g`
Solaris		`netstat -gf inet6`
Linux	`ip -f inet6 addr show`	`netstat -gA inet6` -or- `ip -6 maddr show`
AIX
FreeBSD	`ifconfig -L`	`ifmcstat -f inet6` -or- `netstat -gf inet6` (the latter is deprecated)
Windows	`netsh interface ipv6 show address`	`netsh interface ipv6 show joins`

DHCPv6

OS	Show lease time	Release lease	Renew Lease	Manually start client
Mac OS X	N/A	N/A	N/A
Solaris 10	`netstat -D` -or- `ifconfig XX inet6 dhcp status`	`ifconfig XX inet6 dhcp release`¹	`ifconfig XX inet6 dhcp extend`	`ifconfig XX inet6 dhcp start`
Fedora DHCPv6
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`	`ipconfig /release6`	`ipconfig /renew6`
HP-UX 11i		`dhcpv6client_ui -r`		`dhcpv6client_ui -m XX`

"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".
