Crisp Network Tools.

Flash Fried Daily. Always Fresh.

DNS, whois, mail health, BGP, TCP, TLS, ping, traceroute, port scans, and subnet math. Each check gets its own page, and every result copies cleanly into a ticket.

DNS lookup

Every common record type in one pass, plus subdomains from certificate transparency.

Reverse DNS lookup

PTR names for an IP address, with the command that proves them.

Network whois

RDAP registration for a domain, IP, subnet, ASN, or ARIN handle. Domains resolve to their IPv4 and IPv6 networks.

Mail health check

MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI in one pass, plus PTR and TCP 25 for each mail server.

Common selectors are always tried. Add yours from the s= tag of a message's DKIM-Signature header.

BGP view

Public routing data for an IP, prefix, or ASN: origin, RPKI validity, collector visibility, announced prefixes, and neighbours.

TCP port check

Open a TCP connection to one port and log latency and each attempt.

TLS certificate check

Validity, SANs, issuer, expiry, protocol, cipher, and first-hop HSTS.

Port scanner

Up to 5,000 TCP ports as a list or range like 50-100. Results fill in as each batch finishes.

ICMP ping

Real ICMP echo requests. Copy latency, loss, and every attempt.

Traceroute

ICMP or classic UDP hop path to a host, three probes per hop.

Subnet calculator

IPv4 or IPv6, detected as you type.

Calculated locally in your browser
IPv4

IPv4 or IPv6 is detected automatically. Paste an address or CIDR, then adjust the prefix.

Subnet planner

Start from a master network, reserve and label child blocks, then export the plan as CSV.

Fast network checks, clean output.

Net Bacon is a small set of network checks for technicians and engineers: DNS answers, PTR lookups, network whois, mail health, BGP routing, TCP connects, TLS certificate inspection, port scans, ICMP ping, traceroute, and subnet planning. Results are formatted to go straight into a ticket, change note, or handoff.

One check per page
DNS, PTR, whois, mail health, BGP, TCP, TLS, port scan, ping, traceroute, and IP planning each get their own page and URL.
Protocol-honest
Ping means ICMP. TCP connect means TCP connect. Nothing quietly falls back to something else.
Ticket-ready
Copy the report, the values, the reproducing command, or the raw JSON, depending on who needs the evidence.
Shareable
Every lookup URL reruns the check, and vibePinger boards are shared by link.
