Build Networks From the Ground Up Plan the address space, carve the subnets, and sketch the routing before you touch a switch. A builder's method for IP networks that scale cleanly.

One tap — then see what everyone else is building.
What IPBuilder.com does for you
Size the address space for growth so you never renumber under pressure.
Divide a block into subnets that match how the network is actually used.
Map segments to purposes — users, servers, devices, guests — with clean boundaries.
Choose where routing happens and keep the paths predictable.
Add second paths where failure hurts, not everywhere it looks impressive.
Record the plan so the network survives the person who built it.

How it works
Start from how many devices, sites, and segments you expect in three years, not today.
Core first, then distribution, then edge — verifying each layer before the next.
Every subnet, VLAN, and route gets written down the day it is created.
Questions people ask
Who is IPBuilder for?
Anyone standing up a network — a homelab, a small office, a campus segment — who wants it planned instead of improvised.
Why plan before buying hardware?
An address plan costs nothing to change on paper and a fortune to change in production. Design first, purchase second.
IPv4, IPv6, or both?
Both. Every build guide shows the dual-stack version alongside the v4-only one.
