Can radius be configured to assign ip addresses?

I would need to know if a radius server can be configured in such a way that it allows to assign a specific ip address to a device when it connects. I mean, when a mobile device connects to the wifi network issued by an access point and authenticates through raidus, once that authentication has been successful, give the device a specific ip. If it is possible, how can I make this configuration? by using a pool of ips? Thanks

Generally not unless your wireless access point or wireless lan controller runs a local DHCP server where it pre-populates lease information from Access-Accept packets.

If your WAP/WLC does support this you'll be able to assign addresses by adding the Framed-IP-Address and/or Framed-IPv6-Address attributes to an Access-Accept.

The sqlippool module in FreeRADIUS v3 will be able to do assignments from a pool.

Just to mention. FreeRADIUS v3 supports DHCPv4 natively, and FreeRADIUS v4 supports DHCPv4 and DHCPv6.
