Python IP Doğrulama (IPv4 IPv6 Public Private)

  Ekim 21, 2022      Serkan YILDIZ

 Python içinde hazır gelen Ipaddress modülü bir IP adresini doğrulamak ve tanımlamak için bize yardımcı olacaktır. IP adresi IPv4, IPv6, Public veya private olabilir. Bu ayrımı küçük bir fonksiyon ile anlayabiliriz.

def validate_ip_address(ip_string):
    try:
        ip_object = ipaddress.ip_address(ip_string)
        if ipaddress.ip_address(ip_string).is_private == False:
            if ip_object.version == 4:
                print("IPv4")
                return "IPv4"
            else:
                print("IPv6")
                return "IPv6"
        else:
            print("The IP address is private")
            return "private"
    except ValueError:
        print("The IP address is not valid")
    return "NotValid"

validate_ip_address(192.168.0.1)

Bir IP adresinin Network IP'sini bulmak istiyorsak aşağıdaki kod bize yardımcı olacaktır.

ip_address=192.168.1.55/24
net_ip=ipaddress.ip_network(ip_address, strict=False)
print(net_ip)

IP bilgileri nasıl listelenir:

network = ipaddress.IPv4Network("192.168.1.0/24")

print(network)

# Supernet: 192.168.0.0/23
print("Supernet:", network.supernet(prefixlen_diff=1))
 
# The network is subnet of 192.168.0.0/16: True
print("The network is subnet of 192.168.0.0/16:",
      network.subnet_of(ipaddress.IPv4Network("192.168.0.0/16")))
