I want to get the ip address given url.
I am currently using this
std::string i;
std::string pingStr = (std::string)"nslookup " +"www.yahoo.com" ;
i = system (pingStr.c_str());
but the output is
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
www.yahoo.com canonical name = atsv2-fp-shed.wg1.b.yahoo.com.
Name: atsv2-fp-shed.wg1.b.yahoo.com
Address: 106.10.250.10
Q : Is there anyway I can only get the Ip address ?
使用getaddrinfo(3)函数以可用形式查找IP地址(IPv4或IPv6)。
you can use the folowing command.
nslookup www.yahoo.com | grep Address: | sed -n 2p
grep Address gives you all lines having "address" word in them
sed gets the 2nd line of those 2
You can truncate the "Address" part of output in c++.
