python
import socket
def check_dns_address(domain):
try:
socket.gethostbyname(domain)
return True # DNS address found
except socket.gaierror:
return False # DNS address not found
# Example usage
domain_name = "example.com"
if check_dns_address(domain_name):
print(f"DNS address found for {domain_name}")
else:
print(f"DNS address not found for {domain_name}")
In this code, the `check_dns_address` function takes a domain name as input and attempts to resolve its IP address using `socket.gethostbyname()`. If a `socket.gaierror` exception is raised, it means the DNS address could not be found, and the function returns `False`. Otherwise, if the DNS address is found, it returns `True`.
You can replace `”example.com”` with any domain name you want to check. If the DNS address is found, it will print “DNS address found for {domain_name}”. Otherwise, it will print “DNS address not found for {domain_name}”.
