Why did updates to HOSTS.TXT stop scaling as the network grew?
- Each host uploaded its own full copy
- More hosts downloaded an ever-larger file
- Every lookup crossed the network twice

Answer: More hosts downloaded an ever-larger file. More hosts had to download an increasingly large central file.
The NIC maintained one HOSTS.TXT file that mapped names to addresses, and hosts downloaded updated copies. As the file and network grew, the traffic and central maintenance became impractical; DNS distributed the work.
