How many ZCash full node are there?

My DNS seeder (dnsseed.str4d.xyz) is currently serving 211 zcashd nodes, which it determines are “good” according to these metrics:

zcash/zcash-seeder/blob/6a9baef6dd17f5bffb67de2edd17799f8a182be0/db.h#L104-L120


      
          bool IsGood() const {
            if (ip.GetPort() != GetDefaultPort()) return false;
            if (!(services & NODE_NETWORK)) return false;
            if (!ip.IsRoutable()) return false;
            if (clientVersion && clientVersion < REQUIRE_VERSION) return false;
            if (blocks && blocks < GetRequireHeight()) return false;
          
          
  if (total <= 3 && success * 2 >= total) return true;
          
          
  if (stat2H.reliability > 0.85 && stat2H.count > 2) return true;
            if (stat8H.reliability > 0.70 && stat8H.count > 4) return true;
            if (stat1D.reliability > 0.55 && stat1D.count > 8) return true;
            if (stat1W.reliability > 0.45 && stat1W.count > 16) return true;
            if (stat1M.reliability > 0.35 && stat1M.count > 32) return true;
            
            return false;
          }

GetRequireHeight() currently just returns 0, so partially-synced nodes are not being filtered out. REQUIRE_VERSION is set to the minimum version for the current network (currently 170011 for Heartwood support).
