An occurrence or use of a hardcoded IP address or URL/URI.
Warning locations for this warning class depend on the setting of CSHARP_ANALYSIS_PEDANTIC_MODE.
| CSHARP_ANALYSIS_PEDANTIC_MODE=Yes | A warning is issued when a method that takes a host/hostname
parameter is passed a hardcoded value that matches IP address or
URI/URL format. A warning is not issued for a hardcoded string that matches IP address format unless there is evidence that the string is used as a host/hostname parameter. |
|---|---|
| CSHARP_ANALYSIS_PEDANTIC_MODE=No | A warning is issued for each string literal that that matches
IP address or URI/URL format. There is no requirement that the string be used in a specific context, or even that it be used at all. |
Having a hardcoded IP address is considered a bad practice. It can lead to several problems:
Some security protocols are now considered deprecated and unsafe and so, they must not be used.
