About this utility

How does the IPConfig Analyzer work?

The ipconfig /all command shows adapter-level addressing, DHCP, gateway, and DNS information, but the output is difficult for many users to interpret.

This analyzer separates adapter sections and flags recognizable patterns such as APIPA addresses, missing gateways, and disconnected media.

Adapter separation

Organizes Ethernet, Wi-Fi, VPN, and virtual adapter sections.

Address summary

Extracts recognized IPv4, IPv6, subnet, gateway, DHCP, and DNS fields.

Issue clues

Highlights APIPA, missing gateway, and media-disconnected patterns.

Better results

Best practices before using the result

  1. Paste the complete adapter sections so continuation lines such as secondary DNS servers are included.
  2. Redact host name, DNS suffix, public addressing, and organization details before posting output publicly.
  3. Do not reset Winsock, TCP/IP, or DNS settings until you have recorded the current configuration.

The analyzer reports only evidence found in the supplied content. “Not detected” does not prove a setting, component, or problem is absent.

Common questions

Frequently asked questions

What is an APIPA address?

An IPv4 address in 169.254.0.0/16 is commonly self-assigned when Windows cannot obtain a normal DHCP lease.

Does a missing gateway always indicate a problem?

No. Disconnected, isolated, virtual, and specially configured adapters may not need a default gateway.

Can this tool reset my network?

No. It only analyzes the text you provide.

Is ipconfig output private?

It can reveal local addresses, host names, DNS suffixes, adapters, and organization details, so redact it before sharing publicly.
