IP(8) Linux IP(8)


ip – show / manipulate routing, devices, policy routing and tunnels


ip [ OPTIONS ] OBJECT { COMMAND | help }

ip [ -force ] -batch filename

OBJECT := { link | address | addrlabel | route | rule | neigh | ntable
| tunnel | tuntap | maddress | mroute | mrule | monitor | xfrm
| netns | l2tp | tcp_metrics }

OPTIONS := { -V[ersion] | -h[uman-readable] | -s[tatistics] |
-r[esolve] | -f[amily] { inet | inet6 | ipx | dnet | link } |
-o[neline] | -n[etns] name | -a[ll] | -c[olor] }


-V, -Version
Print the version of the ip utility and exit.

-h, -human, -human-readable
output statistics with human readable values followed by suffix.

-b, -batch
Read commands from provided file or standard input and invoke
them. First failure will cause termination of ip.

-force Don’t terminate ip on errors in batch mode. If there were any
errors during execution of the commands, the application return
code will be non zero.

-s, -stats, -statistics
Output more information. If the option appears twice or more,
the amount of information increases. As a rule, the information
is statistics or some time values.

-d, -details
Output more detailed information.

-l, -loops
Specify maximum number of loops the ‘ip address flush’ logic
will attempt before giving up. The default is 10. Zero (0)
means loop until all addresses are removed.

-f, -family
Specifies the protocol family to use. The protocol family iden‐
tifier can be one of inet, inet6, bridge, ipx, dnet, mpls or
link. If this option is not present, the protocol family is
guessed from other arguments. If the rest of the command line
does not give enough information to guess the family, ip falls
back to the default one, usually inet or any. link is a special
family identifier meaning that no networking protocol is

-4 shortcut for -family inet.

-6 shortcut for -family inet6.

-B shortcut for -family bridge.

-D shortcut for -family decnet.

-I shortcut for -family ipx.

-M shortcut for -family mpls.

-0 shortcut for -family link.

-o, -oneline
output each record on a single line, replacing line feeds with
the ‘\’ character. This is convenient when you want to count
records with wc or to grep the output.

-r, -resolve
use the system’s name resolver to print DNS names instead of
host addresses.

-n, -netns
switches ip to the specified network namespace NETNS. Actually
it just simplifies executing of:

ip netns exec NETNS ip [ OPTIONS ] OBJECT { COMMAND | help }


ip -n[etns] NETNS [ OPTIONS ] OBJECT { COMMAND | help }

-a, -all
executes specified command over all objects, it depends if com‐
mand supports this option.

-c, -color
Use color output.

-t, -timestamp
display current time when using monitor option.

– protocol (IP or IPv6) address on a device.

– label configuration for protocol address selection.

l2tp – tunnel ethernet over IP (L2TPv3).

link – network device.

– multicast address.

– watch for netlink messages.

mroute – multicast routing cache entry.

mrule – rule in multicast routing policy database.

– manage ARP or NDISC cache entries.

netns – manage network namespaces.

ntable – manage the neighbor cache’s operation.

route – routing table entry.

rule – rule in routing policy database.

– manage TCP Metrics

tunnel – tunnel over IP.

tuntap – manage TUN/TAP devices.

xfrm – manage IPSec policies.

The names of all objects may be written in full or abbreviated form,
for example address can be abbreviated as addr or just a.

Specifies the action to perform on the object. The set of possible
actions depends on the object type. As a rule, it is possible to add,
delete and show (or list ) objects, but some objects do not allow all
of these operations or have some additional commands. The help command
is available for all objects. It prints out a list of available com‐
mands and argument syntax conventions.

If no command is given, some default command is assumed. Usually it is
list or, if the objects of this class cannot be listed, help.

Exit status is 0 if command was successful, and 1 if there is a syntax
error. If an error was reported by the kernel exit status is 2.

ip was written by Alexey N. Kuznetsov and added in Linux 2.2.
