IP address to host name conversion
hi, i want to get the hostname for the specified IP address. Code:
# host www.google.com www.google.com has address 173.194.69.104 www.google.com has address 173.194.69.105 www.google.com has address 173.194.69.106 www.google.com has address 173.194.69.147 www.google.com has address 173.194.69.99 www.google.com has address 173.194.69.103 # host 173.194.69.99 99.69.194.173.in-addr.arpa domain name pointer bk-in-f99.1e100.net. Is there any way to get host name as "www.google.com" for the given IP address (173.194.69.99)? "gethostbyaddr" function also returns same host name(bk-in-f99.1e100.net.) as above but i want "www.google.com" as the host name. thanks in advance  Regards, kavitha |

Something like this? Code:
awk '$NF=="173.194.69.99"{print $1}' host_file |

No, actually "173.194.69.99" belongs to google then ,why are we not getting www.google.com as host name other than internal name "bk-in-f99.1e100.net."
is there any function to get actual host names? |

I don't think there is a way. It is up to google what PTR records they provide for reverse lookups. You could use
whois to try and find the IP-address owner..
