Can I put fixed IP address on a device/MAC address?

mariejotje

I have a Sonos speaker linked to my wifi at home. The ip-address is changing sometimes. But w use it in our home automation system. My provider is Telenet. The dhcp server is generating IP-addresses greater the 100. If we put the ip-address on a device under 100 it doesn't change.
On a Sonos system I can not put this fixed. Telenet does'nt offer the option to put a fix ip-address on a MAC address neither. Can I do this via FING, do you have a tool to do this?

Hey @mariejotje
We would not offer this tool/functionality I'm afraid. Apologies for the inconvenience.

@mariejotje, some routers allow you to set an IP address reservation where the device will get the same IP address every time.  In some routers it's called DHCP reservations.  That should solve your issue of the IP address changing as the router will only give it what you reserved.

Thank you Marc , indeed I know, the Telenet router keeps IP-addresses beloofd 100 Free for reservations . But I’m not able to reserve an IP-addresses on the router, and on some devices like a Sonos you can not reserve it neither.

If you can turn off dhcp on the router, you might be able to use something like a Raspberry Pi as a dhcp server on your network. This might the. Allow you reservations across your network, rather than limiting it to a certain range.
