ifconfig add -> resolver error

Hi. I've been having an issue with ifconfig when adding an ip address.
it goes like this:

> ifconfig eth0 add 192.168.1.9
> 192.168.1.9: Resolver Error 0 (no error)

the current interface configuration is as follows:

routing looks like this:

the nameserver in resolv.conf is reachable and working correctly. not
sure what else to include. ifconfig is the version 1.54 supplied with
the release. let me know if you can help!
