https://github.com/LayeredStudio/whoiser/blob/972467452eaae37001e7ab61224675be2576565d/src/whoiser.js#L252

      host = data?.ReferralServer?.split('//')?.[1]

should be followed with

      if (/^rwhois/.test(data?.ReferralServer)) {
            break;
           // or create rwhois parser
      }
      host = data?.ReferralServer?.split('//')?.[1]
