ip hostname

hey guys...i noe this is very basic..
1)but wats ip hostname? i have not come across it...
2)and also should it be in global config mode...so it should be
like this...?
router(config) ip hostname bob 1.1.1.1
or like this

router#
coz in the exam test engine it says it needs to be in global config mode and yet the answer is the 2nd one...

ip hostname ? I think the command you're talking about is 'ip host'.. it doesnt allow you to use 'hostname'. The command just adds a static name to IP mapping.. kinda like DNS, so that you can give names to various IPs. This is useful so you don't have to remember different routers names.

The command has to be used in global configuration mode ie Router(config)#

Heres an example

[code:1]
Router> en
password:

Router# conf t
Router(config)# ip host lara 10.0.0.2
Router(config)# ^Z
%SYS-5-CONFIG_I: Configured from console by console

Router# ping lara

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Router#

[/code:1]

In other words it maps 10.0.0.2 to 'lara' so I can access it using a name rather than an IP.

okye cool!got it

Doh ... Sahir beat me to it :lol:

I've only needed to use the ip host command a few times .. it certainly is not a common command - at least in my world!

lol the first time I used it was to make the post above.. but I did learn about it a while ago. Frankly if you've got the time to sit and name all your routers, you're either damn efficient or don't have much of a networking job. What say ?

Cisco curriculum and certification tests consider ip host as part of the basic configuration of a router. Known as creating a host table. The name you use does not have to be the actual name of the router but the ip address do have to be exact and you can have up to 8 ip addresses associated with the name. Check out this URL.
