Hi Surya, I just tested nslookup on freedom-k64f board and it worked fine:
NuttShell (NSH) NuttX-8.2 nsh> ifconfig eth0 192.168.15.85 nsh> nslookup google.com Host: google.com IPv4 Addr: 216.58.222.78 nsh> nslookup youtube.com Host: youtube.com IPv4 Addr: 172.217.29.78 nsh> ping google.com PING 216.58.222.78 56 bytes of data 56 bytes from 216.58.222.78: icmp_seq=0 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=1 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=2 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=3 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=4 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=5 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=6 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=7 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=8 time=20 ms 56 bytes from 216.58.222.78: icmp_seq=9 time=20 ms 10 packets transmitted, 10 received, 0% packet loss, time 10100 ms nsh> So, probably it is some issues on your configuration.
