I have a list of pc names and ip addresses and some pc names have been seen with more than one IP as they log into our network. I want to strip off all the extra ips and just pull back the first one. 
10.64.160.11, 10.64.161.166, 10.64.184.111, 10.64.184.29

So in the post above, I only want to get 10.64.160.11.
