BlackZeroX (Astaroth) Comprendo, tienes razon, luego se producirian errores logicos, pero mira esta seria una buena correccion !!

printf("Named Server: ");
    gets(ip);
 
    if(strlen(ip)>=15) //comprobamos que nuestro vector no este al limite de caracteres
    {return 1;} //tambien puedes devolver un mensaje avisando de la falta de espacio
 

Si no me equivoco usar cin  con un array de char es lo mismo que usar gets() con el array char (corrijan-me)... lo mejor seria usar el tipo string si se esta en C++.

Extracts characters and stores them as a c-string (i.e. in successive locations starting at location pointed by str and terminated by a null-character). Extraction ends when the next character is either a valid whitespace or a null character, or if the End-Of-File is reached. The terminating null character is automatically appended after the extracted characters.

The extraction operation can be limited to a certain number of characters (thus avoiding the possibility of buffer overflow) if the field width (which can be set with ios_base::width or setw) is set to a value greater than zero. In this case, the extraction ends one character before the count of characters extracted reaches the value of field width, leaving space for the ending null character. After a call to this extraction operation the value of the field width is automatically reset to zero.
