DNS Firewall · Monitoring

See every domain your machines resolve

DNS Proxywall pairs a Windows DNS firewall with built-in DNS monitoring: a live, filterable activity log of every query and response, persistent logs on disk, round-trip timing and country flags — and, on wired networks, visibility into what neighboring computers are resolving.

Live
a real-time activity log with per-status filters

persistent logs keep recording even with the UI closed

round-trip timing to compare upstream DNS servers

Visibility you can’t get from a stub resolver

Windows resolves thousands of names a day and tells you almost nothing about it. DNS Proxywall turns that invisible traffic into a readable log: what was asked for, what answered, how long it took, which country it points to, and whether the DNS firewall let it through or blocked it.

The log is produced by the service component, so monitoring continues whether or not the management window is open, and it can be persisted to disk and rotated daily for later review.

And unlike an online DNS filtering service — which can only show you this history because it routed every query through its own servers first — DNS Proxywall keeps the record private. The activity log lives on your machine, not in a vendor’s cloud dashboard, so you get the visibility without handing your DNS traffic to a third party.

What the monitoring gives you

Live, filterable activity log

Watch queries and responses as they happen, each tagged with a status — queried, resolved, cached, blocked, refused, expired. A filter bar keeps just the events you care about on screen.

Persistent logs & export

Persist the log to disk with daily rotation so it survives restarts, and export it to a file when you need to share it or analyze it elsewhere.

Neighbor monitoring

On a wired network, watch DNS traffic resolved for other computers on the same subnet in promiscuous mode — a fleet-wide view from a single machine. Available in Pro and Ultimate.

Timing & geo context

See per-request round-trip times (with the option to exclude timeouts) to compare upstream servers, and a country flag beside each resolved address for instant geographic context.

From noise to insight in four steps

  1. Turn on the activity log

    Enable logging and pick a view size that suits the machine’s graphics performance.

  2. Make it persistent

    Switch on persistent logging so events are flushed to disk and rotated daily, even with the UI closed.

  3. Filter to what matters

    Use the status filter bar to focus on blocked, remotely resolved or cache-resolved events.

  4. Measure and compare

    Show round-trip times and country flags to benchmark upstream servers and spot anomalies.

What the log can tell you

Question Where the answer is
What is this machine resolving right now? The live activity log, filterable by status
What got blocked, and why? Per-record status: name-pattern, geo, cache-only, timeout and more
Which upstream DNS server is faster? Round-trip timing, optionally excluding timeouts
What are other PCs on the wire resolving? Promiscuous neighbor monitoring (Pro / Ultimate)
Can I keep a record? Persistent, daily-rotated logs plus file export
Where do the logs live? On your own machine — not in an online provider’s cloud dashboard

DNS monitoring questions

What does DNS monitoring show?

DNS Proxywall records each DNS request and response with a status that shows whether it was queried, resolved remotely, resolved from cache, resolved from the host address table, blocked, refused or expired. Status filters let you keep only the events you care about in view.

Can it keep logs for later analysis?

Yes. The activity log can be made persistent and is flushed to disk and rotated daily by the service component, so it keeps recording even when the user interface is closed. Logs can also be exported to a file.

Can it see DNS activity from other computers?

On a wired network, DNS Proxywall can monitor DNS traffic between other computers on the same subnet in promiscuous mode, in addition to the local machine’s own queries. This feature is available in the Pro and Ultimate editions.

Does it measure DNS performance?

Yes. DNS Proxywall measures the round-trip time of DNS requests and can exclude timeouts from the average, helping you compare upstream servers and spot slow resolution.
