Frequently asked questions

What should be in a basic network documentation pack?

Site list, WAN circuit details, LAN subnets, gateway IPs, DNS servers, VLAN map, equipment inventory and credentials reference (kept separately). Diagrams are a plus.

Why keep printed copies of network maps?

When everything is down — including the wiki — printed maps and a phone are how you survive the first hour of a major outage.

How often should network docs be refreshed?

After every change ticket. A quarterly review catches the drifts that ticket-by-ticket edits miss.

Which fields matter most to an incoming engineer?

Site list, contact escalation tree, WAN provider tickets, default gateway / DNS, and out-of-band access methods.
