Bazen belirli bir IP‘nin hangi kuruma ait olduğu hangi IP aralığında olup olmadığını veya belirli bir ASN’ye ait olup olmadığını tespit etmemiz gerekir.
Bunun en kolay yollarından bir tanesi ise whois aracını kullanmaktır.
Dig ile DNS ve diğer bilgileri getiriyoruz.
dig turktelekom.comÇıktısı aşağıdaki gibi olacaktır.
