Get specific PC IP from "arp -a"

I want to extract IP of machine leonidas. arp -a returns such line (among others): 
leonidas.home (192.168.1.5) at 0:1c:c0:de:8f:28 on en1 ifscope [ethernet] 

 To have only IP:
arp -a | grep leonidas | cut -f 2 -d ' ' | sed 's/[()]//g'
prints
192.168.1.5
at

    easier way:
    arp | grep wlan0 | awk '{print $1}'

    use host name rather than interface name
