Fix IP on a wireless network

garywork · 9 Mar 2013 at 17:29

Hi

if you fix your IP on your internal network to say 192.168.1.12 and the router is providing dynamic ips for the rest of the devices - what is to stop 192.168.1.12 being allocated first to another machine then you log on and try and set that IP as your own fixed one ?

just thinking, if I set mine to a high no. (12 isnt bad anyway) say 192.168.1.55 I could be pretty sure that no one would be allocated 192.168.1.55 ?

any networking bods agree with this ?

also, maybe option to fix the ip on every device on the network but that doesn't sound a good idea

this is a home network so experimental use really - portforwarding to 1 pc only

thanks

Generally speaking once your machine has joined the network at least once the IP address won't be reused.

Change the DHCP scope if you want to do it the proper way.

Some let you reserve addresses as well.

Hi

its a HG533 Huawei TalkTalk - didnt know you could give a range to DCHP - i'll have a look

just checked (its 1.14 firmware, much faster than 1.13 menu wise)

Basic > LAN > DHCP

DHCP Server
Help
DHCP server: Enable
Start IP address: 192.168.1.2
End IP address: 192.168.1.254

so I could limit the End IP address to say 192.168.1.100 and fix mine as 192.168.1.120 ?

Yes.

Or add a DHCP reservation.

Excellent

Sin Chase - just as I scrolled down the page i see (new to this router) :-

DHCP Option Pool
Device type:
Option60:
Start IP address: *
End IP address: *
DHCP relay: Enable

IP Address Reserve
New Remove Help
Index MAC address: IP address

IP Address Reserve looks good enough for me at the moment

Is this sort of level covered in dummies networking type of books ?

Thanks for your help guys
