You'd block google's DNS servers with that, which might not be a problem on the client, but may I suggest a "new and improved" method:

host youtube.com | awk '/has address/ {print $NF}'
74.125.228.5
74.125.228.3
74.125.228.1
74.125.228.14
74.125.228.0
74.125.228.8
74.125.228.2
74.125.228.6
74.125.228.4
74.125.228.9
74.125.228.7


Remove the awk filter and you'll also see the IPv6:

youtube.com has IPv6 address 2607:f8b0:400d:c00::5d
