This terraform-plugin-sdk (v1) analyzer has been removed in tfproviderlint v0.30.0.
The V003 analyzer reports usage of the deprecated IPRange validation function that should be replaced with IsIPv4Range.
ValidateFunc: validation.IPRange(),
ValidateFunc: validation.IsIPv4Range,
Singular reports can be ignored by adding the a //lintignore:V003
Go code comment at the end of the offending line or on the line immediately proceding, e.g.
//lintignore:V003
ValidateFunc: validation.IPRange(),
