For inter­nal ser­vices, you prob­a­bly want to have them fail over between sites. Dynamic rout­ing pro­to­cols will let you do that.

If you use a loop­back inter­face for your ser­vice, you can share the IP address between two dif­fer­ent servers, even on the same LAN.

A nifty hack that’s pos­si­ble in IP net­works is the abil­ity to share an IP between servers thou­sands of miles apart.

Anycasting is a way to scale geo­graph­i­cally by hav­ing mul­ti­ple servers shar­ing the same IP address.
