Move a value. See an idea.
Small, local experiments. Change one thing and notice what changes with it.
These simplified models are for learning. They do not configure equipment or replace engineering calculations.
An address finds its neighbourhood.

- Broadcast
- Host range
- Usable addresses
/31 assumes a point-to-point link; /32 represents one host. This calculator does not assign addresses or assess routability.
A small circuit, a clear relationship.
- Current
- Power
Ideal, steady DC resistor only. Marker rate is proportional to conventional current, not actual electron speed. No heating, tolerances, wiring or battery limits are modelled.
Even light needs time.
1 AU = 149,597,870.7 km exactly, approximately the mean Earth–Sun distance. 2 AU = 299,195,741.4 km. Light needs about 8 min 19 s per AU.
A 0.6 s pause at the destination separates each pulse; it is not part of light travel time.

Straight-line travel in vacuum: t = d / c. The line always represents the selected distance; objects are not drawn to scale. Radio routing and processing add delay.
