IP(8)

NAME
ip - show / manipulate routing, devices, policy routing and tunnels

SYNOPSIS
ip [ OPTIONS ] OBJECT { COMMAND | help }

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

OPTIONS := { -V[ersion] | -s[tatistics] | -r[esolve] | -f[amily] { inet | inet6 | ipx | dnet | link } | -o[neline] }

OPTIONS

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

-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.

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

-f, -family
    followed by protocol family identifier: inet, inet6 or link ,enforce the protocol family to use. If the 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 involved.

-4  shortcut for -family inet.

-6  shortcut for -family inet6.

-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(1)
     or to grep(1) the output.

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

IP - COMMAND SYNTAX

  OBJECT

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

addrlabel
    - label configuration for protocol address selection.

l2tp
    - tunnel ethernet over IP (L2TPv3).

link
    - network device.

maddress
    - multicast address.

monitor
    - watch for netlink messages.

mroute
    - multicast routing cache entry.

mrule
    - rule in multicast routing policy database.

neighbour
    - 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.

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, f.e. address is abbreviated as addr or just a.

  COMMAND
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 commands 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.

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