I'm confused as to why it would block the Google DNS servers (which I believe are 8.8.8.8 and 8.8.4.4 unless they have more? resolve to):
8.8.8.8.in-addr.arpa. 43194 IN PTR google-public-dns-a.google.com. My results to both of our suggestions seem to be identical. Very interesting that we get completely different results though. :-) [mianosm@dev ~]$ host youtube.com | awk '/has address/ {print $NF}' 173.194.37.100 173.194.37.105 173.194.37.96 173.194.37.104 173.194.37.102 173.194.37.101 173.194.37.99 173.194.37.110 173.194.37.98 173.194.37.103 173.194.37.97 [mianosm@dev ~]$ dig youtube.com | egrep youtube.com | awk '{ print $5 }' | grep -v '<<' | grep . 173.194.37.100 173.194.37.105 173.194.37.96 173.194.37.104 173.194.37.102 173.194.37.101 173.194.37.99 173.194.37.110 173.194.37.98 173.194.37.103 173.194.37.97 On Thu, Oct 4, 2012 at 11:27 AM, Chris Schanzle <schan...@nist.gov> wrote: > On 10/04/2012 09:58 AM, Steven Miano wrote: > >> dig youtube.com <http://youtube.com> | egrep youtube.com < >> http://youtube.com> | awk '{ print $5 }' | grep . | grep -v '<<' > yt.dig >> > > 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 > -- <http://stevenmiano.com/> Miano, Steven M. http://stevenmiano.com
