Simple IP Filter for ASP.NET Core.

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

    // (...)

    var filters = Configuration.GetIpFilters("IpFilters");
    var options = Configuration.GetIpFilterOptions("IpFilterMiddlewareOptions");

    app.UseIpFilter(filters, options);


filters and options can be read from configuration:

    "ExactPathMatch": false,
    "LogRequests": true,
    "ApplyOnlyToHttpMethod": "", 
    "ResponseHttpStatusCode": 401
