Rule Definition
Built-in remote addresses cause problems when the target is moved. Avoid hardcoded network resources (e.g., IP addresses, URLs, etc.)

Remediation
Utilize indirect access to network resources using underlying operating system calls and relative paths. In case hard coding is necessary, isolating hard coded data to installation scripts or configuration files can limit its potential negative impact.

Violation Code Sample

var ipv4 = "193.43.55.67";
...
ipv4 = "193.43.55.67";
...
var ipv6 = "2001:db8:0:85a3:0:0:ac1f:8001";
...
ipv6 = "2001:db8:0:85a3:0:0:ac1f:8001";
...

var ipAddress = IPAddress.Parse("193.43.55.67");

Fixed Code Sample

var ipv4 = ConfigurationManager.AppSettings["appIP"];
...
ipv4 = ConfigurationManager.AppSettings["appIP"];
...
var ipv6 = ConfigurationManager.AppSettings["appIP"];
...
ipv6 = ConfigurationManager.AppSettings["appIP"];
...

var ipAddress = ConfigurationManager.AppSettings["appIP"];
