Ranks Per World

I know in the popular servers you go to there server shop in there website And then they have a Factions Category and perhaps you buy Rank A on FactionsA & Then Rank B on FactionsB And then when you log in to Factions A You have Rank A & It doesn't conflict with the other ranks. So you can Have Different ranks & Prefixes on each world. How Is this possible? Does anyone know? Is this some plugin or something..? So basically I'm asking how can you have Different ranks for each world? So if someone has a SkyWars rank they wont have a Factions Rank on the SkyWars World. Does anybody know how to do this? (Is this BungeeCord or something?) Please help! Would be a great help
