AğCIDR / Alt Ağ Hesaplayıcı
Herhangi bir IPv4 CIDR bloğunu ağ ve yayın adreslerine, kullanılabilir ana bilgisayar aralığına, ana bilgisayar sayısına ve ağ maskesine ayır. Tamamen tarayıcında çalışır.
Ağdig output explainer
Paste real dig output and get a decoded, explained breakdown: the header and flags, the EDNS OPT pseudo-section, every record in each section, and the query stats. Parsed entirely in your browser, nothing is resolved or sent anywhere.
AğHTTP methods comparison
Enter one to four HTTP methods (try "get vs query") to see each one's registry facts: safe, idempotent, cacheable, request-body semantics, CORS safelist membership, HTML-form support, and the defining RFC - plus exactly which properties differ. Includes QUERY, the RFC 10008 method registered in June 2026.
AğHTTP status code explainer
Paste status codes (404, 301 302 307) or families (5xx) and get each one decoded: family, registered name, documented meaning, and the operational notes - including the protocol's own fallback rule for codes it has never met.
AğIPv6 Araç Takımı
Kanonik (RFC 5952) ve tam genişletilmiş biçimlerini, özel kullanım sınıflandırmasını, önek aritmetiğini, varsa bir EUI-64 MAC'i ve ip6.arpa ters DNS adını görmek için bir IPv6 adresi ya da öneki ayrıştır. Tamamen tarayıcında çalışır.
AğMTU / MSS calculator
Enter a link MTU and your encapsulation stack (vxlan, gre, pppoe, vlan, mpls, +N custom) to get the inner MTU and TCP MSS, the Ethernet frame sizes, the underlay MTU an overlay needs, and the wire efficiency of standard versus jumbo frames.
Ağnslookup output explainer
Paste real nslookup output and get a decoded, explained breakdown: the resolver it used, whether the answer is authoritative, every record (with MX / SRV / SOA field breakdowns), and any failures. Parsed entirely in your browser, nothing is resolved or sent anywhere.
AğOUI / MAC vendor lookup
Look up the manufacturer behind a MAC address, and read whether it is unicast or multicast and universally or locally administered. All in your browser.
Ağp0f passive TCP/IP signature explainer
Decode a p0f v3 SYN fingerprint into its eight fields and see what each reveals about the sender's OS, network path, and stack.
AğZscalerPAC file explainer and validator
Paste a Proxy Auto-Config file and it reads back the proxy directives it returns, the PAC helper functions it uses (with the DNS-consulting ones flagged), structural and correctness lints, and whether it is a Netskope explicit-proxy steering file. Never runs the file.

Operations & Fieldcraft
Before/After Health Snapshot Comparator
You declare the states, the tool gates the conclusion: seven selections produce a tiered comparison report - baseline quality, a churn-classed dimension catalog, delta-interpretation guidance, and the continue / observe / investigate / hold-rollback-ready gate. Never labels a change successful on green components alone.
Operations & FieldcraftChange Blast-Radius Mapper
Describe what you are changing and its structure; a fixed rule set maps the blast radius as concentric tiers (target, co-located, downstream, human) populated with what could be affected, plus severity-tagged risks and containment measures. It maps what could be affected, never asserts what will break.
Operations & FieldcraftChange Window Runbook Builder
Describe a planned change in six structured fields; a fixed rule set assembles an ordered runbook across six phases - with the risks the plan carries and readiness cautions about the input. Advisory structure to review and adapt, never an approval.
Operations & FieldcraftDigital transformation tracker
Thirty milestones across seven domains, sorted by how much you should trust them: what shipped, what is already law, what is scheduled, what is scheduled but actively moving, and what is only somebody's forecast.
Operations & FieldcraftFault Hypothesis Builder
Describe a fault in six structured fields; a fixed rule set ranks hypotheses to test - with the evidence to collect, what would support each, and what would weaken it. Advisory structure, never a diagnosis.
Operations & FieldcraftFlow Path Reasoner
The senior skill is refusing to troubleshoot until the path is understood. Seven selections build a canonical hop map with side-flows, TLS segments, rewrite points, and ranked failure-domain candidates - and unknowns stay visibly unknown.
Operations & FieldcraftIncident Timeline & RCA Builder
RCA stands for root cause analysis - the disciplined walk from an incident's symptoms back to the conditions that allowed it. Enter an incident's events as a small timeline and mark the contributing-factor domains you observed; a fixed rule set orders the timeline, derives the milestone spans, and structures candidate contributing factors with the evidence for each. It never names a root cause - candidates to investigate, not a verdict.
Operations & FieldcraftNetwork operating system comparer
Fourteen network operating systems — IOS, IOS XE, IOS XR, NX-OS, Junos, Junos Evolved, EOS, TMOS, F5OS, EXOS, VOSS, FortiOS, PAN-OS and Gaia — with lineage, what each runs on, how components share state, where the planes divide, and what an upgrade costs. Pick one for a full profile or two to see them axis by axis. Every entry lists weaknesses as well as strengths.
Operations & FieldcraftPacket Capture Plan Builder
Command builders answer how to capture; this answers where, why, and what it would mean. Describe the path and the symptom; a 35-rule original registry designs a phased capture plan: ranked points on named boundaries, expected observations, an interpretation matrix with supports and weakens decided before collection, and sync/authorization discipline. It plans captures - it never ingests them.
Operations & FieldcraftTAC Escalation Packet Builder
Describe the issue you are about to escalate; a fixed rule set assembles a complete vendor-support packet and a checklist of the artifacts still to collect before opening the case, dropping what you already have. It structures the hand-off; it does not open a case or contact any vendor.
Operations & FieldcraftTerminal, shell, TTY and console explainer
Paste what `tty` printed — /dev/pts/3, /dev/tty2, /dev/ttyS0, /dev/tty, /dev/console, or “not a tty” — and see which layer you are actually looking at, what is holding the other end, and what that implies for signals, job control and what happens when the window closes. Local and offline.

Security & WAFHTTP header-order fingerprint
Paste a request header block and see how header order and casing fingerprint the client - the passive-HTTP analog of JA3.
Security & WAFZscalerPing IdentityJA3 / JA3N passive TLS fingerprint
Paste a JA3 string and it recomputes the JA3 hash, computes the permutation-stable JA3N, decodes the fields, and flags GREASE values.
Security & WAFZscalerPing IdentityJA4 / JA3 TLS fingerprint decoder
Decode a JA4 TLS client fingerprint or a JA3 fingerprint into its fields, compute the hashed JA4 from raw values, or compute a JA3 MD5. It auto-detects which you paste. All in your browser.
Security & WAFZscalerPing IdentityOGNL injection decoder
Paste an OGNL payload you found in a WAF or application log and read what it was trying to do. Separates a sandbox escape from an execution call, names the advisory family the shape is consistent with, and always states what it did not determine. Decodes only - it never evaluates the payload and holds no templates.
Security & WAFSecure Headers Analyzer
Paste an HTTP response and get a graded breakdown of its security headers, cookie flags, and cross-origin policy, checked against OWASP, RFC 6797, CSP Level 3, and RFC 6265bis.
Security & WAFSSRF URL classifier
Paste a URL and see where it actually points: loopback, a private or link-local range, a cloud metadata endpoint, CGNAT, reserved space, or the public internet. Decimal, octal, and hex IP obfuscation is decoded, dangerous schemes and embedded credentials are flagged, and an SSRF risk level is shown. It never resolves DNS and never sends the request.
Security & WAFUser-Agent entropy analyzer
Paste a User-Agent string and see the identifying tokens it exposes, the distinguishing bits each contributes, and the Client Hints migration.
Security & WAFZscalerPing IdentityXML Decoder
Paste XML and read its structure: the declaration, the DOCTYPE and any entities, the element tree with namespaces and attributes, plus a security check of the XML attack surface. Nothing is fetched or resolved.
