I'm looking for the best way to get multiples websites IPs and output them as "domain.com:","1.1.1.1" in order to achieve this I was thinking on using nslookup (not sure if is the best option but I don't want to use ping)
Well I was trying something like:
for domain in $(cat domains.txt)
do
nslookup $domain 8.8.8.8 | awk '/Address: ([[:digit:]]+\.){3}/{gsub(/\.$/,"",$1); printf "\"%s\",\"%s\"\n",$1,$NF}'; done
With this, I'm get this output:
"Address:","64.233.190.101"
"Address:","64.233.190.138"
"Address:","64.233.190.100"
"Address:","64.233.190.139"
"Address:","64.233.190.113"
"Address:","64.233.190.102"
"Address:","98.137.246.8"
"Address:","98.138.219.231"
"Address:","72.30.35.9"
"Address:","72.30.35.10"
"Address:","98.138.219.232"
"Address:","98.137.246.7"
"Address:","93.184.216.34"
Expected Output
"google.com","64.233.190.101"
"google.com","64.233.190.138"
"google.com","64.233.190.100"
"google.com","64.233.190.139"
"google.com","64.233.190.113"
"google.com","64.233.190.102"
"yahoo.com","98.137.246.8"
"yahoo.com","98.138.219.231"
"yahoo.com","72.30.35.9"
"yahoo.com","72.30.35.10"
"yahoo.com","98.138.219.232"
"yahoo.com","98.137.246.7"
"example.com","93.184.216.34"
domains.txt content:
google.com
yahoo.com
example.com
I was trying to do this but I can’t get the correct domain under "domain.com", on the output.
I'm not sure if using $domain or awk, Can any one help me to get the correct syntax. Please note that I need requested domain inside "domain.com", not the Name: in nslookup
Thanks.
domain="mail.yahoo.com"
nslookup "$domain" 8.8.8.8 | awk -v n="$domain" -F ' +' '$1=="Address:"{print "\""n"\",\""$2"\""}'
Output:
"mail.yahoo.com","87.248.116.12" "mail.yahoo.com","87.248.116.11"
