socket.gethostbyname [Errno -2] Name or service not known

Question

I was trying to check a few domain names but even some common one are returning this

the error occurs in "df['IPaddr'] = socket.gethostbyname(DN)"

So I tried to try: but most of them are failing!

checked domain

Unexpected error:

AMD.com

Unexpected error:

allow_permutations=True doesn't look like a valid parameter for IPWhois. Because you're using try you might not be seeing the TypeError:

TypeError: __init__() got an unexpected keyword argument 'allow_permutations'

Once I remove that parameter, everything works as expected for me:

from ipwhois import IPWhois
import socket
DN = 'AMD.com'

ip = socket.gethostbyname(DN)
ipwhois = IPWhois(ip).lookup_whois()

print(ip)
print(ipwhois)

If you're still having trouble, there may be a DNS or routing issue causing problems. A quick way to isolate whether your local environment is the issue or not is to test your code snippet in something like Google Colab since the runtime will be on Google servers: https://colab.research.google.com/

If neither of these suggestions work, you'll have better luck removing the try statement or print the exception to the console and post the error you receive here:

try:
  ip = socket.gethostbyname(DN)
  ipwhois = IPWhois(ip, allow_permutations=True).lookup_whois()
  print(ip)
  print(ipwhois)

except Exception as e:
  print(e)
