types/netmap/netmap.go:238–249

PeerIndexByNodeID returns the index of the peer with the given nodeID in nm.Peers, or -1 if nm is nil or not found. It assumes nm.Peers is sorted by Node.ID.

(nodeID tailcfg.NodeID)

		return -1

// MagicDNSSuffix returns the domain's MagicDNS suffix (even if MagicDNS isn't
