Audit the security of your IP, domain and email in seconds.

IP

IP Lookup

Identifies whether an IP is public, private or reserved and queries RDAP data such as ASN, organization, network range and reverse hostname when available.

Operational Use

RE

Reverse DNS

Queries the PTR record of a public IP to see which hostname is declared by the range owner. Useful for logs, email, reputation and provider identification.

Operational Use

CI

CIDR Calculator

Calculates network address, broadcast, netmask, wildcard, host count and usable range from an IPv4 network in CIDR notation.

Operational Use

IP

IPv4 Converter

Converts an IPv4 address to decimal, hexadecimal and per-octet binary for firewall rules, inventories or systems that store IPs as integers.

Operational Use

PO

Port Scanner

Checks common ports on authorized domains or IPs to detect exposed services such as web, SSH, mail, databases or remote administration.

Operational Use

PI

Ping

Measures latency, basic loss and host availability to separate real outages from local resolution or connectivity issues.

Operational Use

TR

Traceroute

Shows network hops to a destination to investigate slow routes, intermediate outages or provider differences.

Operational Use

IP

IPv6 Test

Checks whether a domain publishes an IPv6 address (AAAA record). DNS-level check, no real IPv6 connectivity test.

Operational Use

DN

DNS Lookup

Queries A, AAAA, MX, TXT, NS, CNAME and SOA records to diagnose hosting, email, domain verification and zone changes.

Operational Use

MX

MX Lookup

Reviews which servers receive email for the domain, their priority and whether the setup points to expected providers.

Operational Use

TX

TXT Lookup

Shows text records published in DNS, including SPF, provider verifications, email policies and configuration signals.

Operational Use

DN

DNSSEC Check

Checks whether the domain is DNSSEC-signed according to Google and Cloudflare's public resolvers.

Operational Use

DN

DNS Propagation

Compares DNS answers between Google and Cloudflare to confirm whether a recent change has propagated or still returns inconsistent answers.

Operational Use

DO

Domain Health

Combines DNS, SSL, HTTP and domain blacklist status into one technical health view with prioritized findings.

Operational Use

SP

SPF Checker

Checks whether the domain publishes a valid SPF record to authorize outgoing mail servers.

Operational Use

DK

DKIM Checker

Reviews common DKIM selectors and published keys to confirm whether outbound email can be signed correctly.

Operational Use

DM

DMARC Checker

Evaluates the published DMARC policy (none, quarantine, reject) and its spoofing protection level for the domain.

Operational Use

MX

MX Health

Checks resolution, priority and blacklist status of the primary MX to detect domains without functional email or misconfigured providers.

Operational Use

SM

SMTP Test

Validates SMTP connectivity, banner and STARTTLS support of the mail server, without sending email or attempting authentication.

Operational Use

EM

Email Security Check

Groups MX, SPF, DKIM, DMARC and STARTTLS into a single score to measure basic spoofing and deliverability risk.

Operational Use

SS

SSL Checker

Reviews issuer, covered name, validity dates and days remaining before the active TLS certificate expires.

Operational Use

HT

HTTP Headers

Shows visible headers returned by the server to understand cache, technology, redirects and HTTP behavior.

Operational Use

SE

Security Headers

Checks defensive headers such as HSTS, CSP, X-Frame-Options, Referrer-Policy and Permissions-Policy, with risk context.

Operational Use

TL

TLS Checker

Detects which TLS versions the server accepts, flagging old protocols like TLS 1.0 and 1.1 as a risk.

Operational Use

RE

Redirect Checker

Follows the redirect chain to find loops, unnecessary hops or HTTPS loss.

Operational Use

HS

HSTS Checker

Checks whether the site enforces HTTPS with HSTS, suitable duration, includeSubDomains and preload list status.

Operational Use

OP

Open Ports

Identifies exposed common services and helps prioritize closure or restrictions when administration or database ports appear.

Operational Use

RE

Reputation Check

Queries public DNSBL blacklists to detect whether an IP or domain appears reported for spam or abuse.

Operational Use

MA

Malware Domain Check

Looks for malicious-domain indicators on Spamhaus DBL, a public list associated with spam, phishing and malware.

Operational Use

PH

Phishing Indicators

Evaluates basic impersonation signals such as similar names, weak email configuration and missing anti-spoofing controls.

Operational Use

TE

Technology Detection

Detects technologies visible through headers and public HTML to help inventory stack, CMS and web surface.
