About this category
Store passwords in a manager. UUIDv4 is an identifier, not a login secret. Random IPs are syntax examples — prefer documentation ranges like 192.0.2.0/24 when teaching.
For a giveaway, publish your method. A webpage draw is fine for a classroom; high-stakes prizes need a process your audience trusts.
