IPv4 CIDR & ranges
Network, broadcast, wildcard, usable hosts, masks and binary.
OPEN TOOL →Subnet planning, IP analysis, troubleshooting, reference data and command generation — all in one local-first browser tool.
Network, broadcast, wildcard, usable hosts, masks and binary.
OPEN TOOL →Allocate subnets from host requirements, largest-first.
PLAN NETWORK →Spider public sites, flag failures, redirects, broken images and link problems.
CRAWL WEBSITE →Recognizes ipconfig, ping, tracert, nslookup and common failures.
ANALYZE OUTPUT →Session data is stored only in this browser unless you export a report.
Mark each checkpoint Pass, Fail, or Not Tested. NetMedic will suggest the most likely fault domain and next action.
Start with physical/link state, then addressing, gateway, DNS, and application reachability.
Complete or fail checklist items and add evidence to let NetMedic correlate the fault domain.
ipconfig /all
Examples:
Staff, 120
Guest WiFi, 60
Printers, 18
NetMedic sorts by requirement and assigns the smallest valid subnet for each segment.
| Segment | Needed | Subnet | Usable Range | Capacity |
|---|
DNS lookups require Internet access. The queried hostname is sent to a public DNS-over-HTTPS resolver; other NetMedic analysis remains local.
Yes — type a hostname such as fark.com and NetMedic can resolve its current IPv4 A record without a backend server.
A site may return several addresses, CDN addresses, or no A record at all. Results can change over time.
Enter a hostname and choose a DNS record type.
| Port | Protocol | Service | What it is |

Paste command output and NetMedic will identify useful signals and likely next steps.
NetMedic calculates loss and latency from pasted command output.
NetMedic extracts hop numbers, addresses, latency and timeout patterns.
NetMedic identifies IPv4 addresses, masks, gateways, DNS and common configuration problems.
NetMedic identifies default routes, gateways, interfaces and route selection clues.
NetMedic summarizes open and filtered services and flags exposure worth reviewing.
The report correlates evidence and avoids claiming certainty when a layer was not tested.
NetMedic will correlate addressing, gateway, DNS, loss, routing and service clues.
Run an audit to build an infrastructure health profile.
Enter a public URL to begin.

Browsers cannot bypass another site's CORS policy. Exact status codes are shown only when NetMedic directly receives them. Reader fallback is useful for discovering public page links, but those entries are marked PROXY and are not represented as exact origin HTTP status unless directly verified.
Use the crawler only on sites you are authorized to test. Large production crawls are better handled by a server-side crawler.
