pingtrace

pingtrace runs ping and traceroute from a single command and enriches every reply and hop with DNS, organisation, ASN, geolocation, and PeeringDB data.

It accepts:

1. Single target - pingtrace 8.8.8.8
2. Multi-target - comma-separated: pingtrace 8.8.8.8,1.1.1.1,example.com
3. CSV file - pingtrace --file targets.csv (first column is the target)
4. IPv4 CIDR - pingtrace 10.0.0.0/30 (auto-switches to bulk mode for /23 and larger)

Output is rendered as a responsive table that adapts to your terminal width, with optional CSV export for reporting.

Why pingtrace

You want to	Without pingtrace	With pingtrace
Ping + traceroute one host	Two commands, two cli outputs	One command, two tables exportable in csv
Know the ASN/org behind each hop	Manual whois per IP	Built-in via ipinfo.io
Spot a CDN vs a transit hop	Cross-reference PeeringDB by hand	net_type/policy columns
Check a whole /24	Shell loop + manual CSV	pingtrace 10.0.0.0/24 -> CSV
Resolve hops against an internal DNS	dig @internal.dns ... per hop	dns.privateServers config

Install

npm install -g pingtrace
pingtrace --help

Or run without installing:

npx pingtrace 8.8.8.8

Quick start

Targets

pingtrace 8.8.8.8                              # single host
pingtrace 8.8.8.8,1.1.1.1,example.com          # multiple hosts
pingtrace 10.0.0.0/30                          # IPv4 CIDR
pingtrace --file ./targets.csv                 # from CSV

CSV input format - one target per row, first column only:

target
8.8.8.8
1.1.1.1
example.com

Operations

pingtrace 8.8.8.8 --no-trace      # ping only
pingtrace 8.8.8.8 --no-ping       # trace only

Output

pingtrace auto-fits its tables to your terminal width. When space is tight, it drops the lowest-priority enrichment columns (policy, net_type, private_dns, location, asn, org, public_dns in that order) and truncates long values with an ellipsis. The essentials (seq/hop, ip, time/probe_*_ms, status) are always preserved.

pingtrace 8.8.8.8 --summary                          # one line per target
pingtrace 8.8.8.8 --wide                             # disable auto-fit, full width
pingtrace 8.8.8.8 --columns seq,ip,time_ms,status    # render only these columns

Export

pingtrace 8.8.8.8 --export              # CSV in current directory
pingtrace 8.8.8.8 --export ./reports    # CSV in ./reports

When export is enabled, pingtrace writes one file per operation:

• ping_UTCdate(YYYY-MM-DD-HH-MM-SS).csv - one row per packet, with all enrichment columns
• trace_UTCdate(YYYY-MM-DD-HH-MM-SS).csv - one row per hop, with all enrichment columns

With --summary, the CSV falls back to one summary row per target instead of per-packet/per-hop detail.

Config

Open the interactive editor:

pingtrace config

List current values:

pingtrace config list

Set a single value directly:

pingtrace config set ping.packetCount 3

Examples for DNS server target lists:

pingtrace config set dns.publicServers 8.8.8.8
pingtrace config set dns.publicServers 8.8.8.8,1.1.1.1
pingtrace config set dns.privateServers 10.0.0.0/30

Supported config keys:

Key	Default	Description
dns.privateServers	(empty)	Private/internal DNS servers for reverse lookups. Accepts IPs, comma-separated IPs, or CIDR.
dns.publicServers	8.8.8.8	Public DNS servers for reverse lookups.
providers.ipinfoToken	(empty)	ipinfo.io API token. Enables org, asn, and location columns for public IPs.
providers.peeringdbEnabled	false	Enables PeeringDB enrichment. Adds net_type and policy columns for public IPs. Requires providers.ipinfoToken.
ping.packetSize	56	Ping packet size in bytes.
ping.packetCount	4	Number of ping packets per target.
ping.timeoutSeconds	5	Ping timeout in seconds.
trace.maxHops	16	Maximum traceroute hops.
trace.timeoutSeconds	2	Per-hop traceroute timeout in seconds.
trace.numericOnly	true	Skip hostname resolution in traceroute.

Enrichment

Output columns are shown conditionally - only when the corresponding provider is configured.

DNS

Reverse DNS lookups are performed for every hop and ping reply. Configure up to two resolvers:

pingtrace config set dns.privateServers 10.0.0.1   # internal resolver
pingtrace config set dns.publicServers 8.8.8.8      # public resolver

If a private DNS server is unreachable, pingtrace will warn and skip it after a 5-second timeout so probes continue without interruption.

ipinfo.io

Enriches public IPs with organisation, ASN, and geolocation. Get a free token at ipinfo.io.

pingtrace config set providers.ipinfoToken <your-token>

Adds columns: org, asn, location.

PeeringDB

Enriches public IPs with network type and peering policy sourced from the PeeringDB public API. Requires providers.ipinfoToken to resolve the ASN first. No additional credentials are needed for PeeringDB.

pingtrace config set providers.peeringdbEnabled true

Adds columns: net_type, policy.

net_type value	Meaning
NSP	Network Service Provider - transit/backbone carrier
Content	Content delivery network (CDN) or hyperscaler
IXP	Internet Exchange Point
Enterprise	Enterprise or corporate network
Educational	University or research network
Non-Profit	Non-profit organisation
Route Server	Route server operator

policy value	Meaning
Open	Will peer with anyone
Selective	Peers on a case-by-case basis
Restrictive	Very limited peering
No	Does not peer

Bulk mode

When a target set exceeds 254 hosts (i.e., any CIDR larger than /24 such as /23, /22, /18), pingtrace automatically enables bulk mode:

• Streaming tables are disabled - output is one compact summary line per target
• Up to 10 probes run concurrently to reduce total execution time
• A CSV is auto-exported to the current directory without requiring --export

pingtrace 10.0.0.0/22

pingtrace
Targets: 1022
Operations: ping, trace
Bulk mode: 1022 targets exceed /24 - running concurrently, streaming disabled.
CSV export: /current/dir
Running probes...

  10.0.0.1            ok ping: loss 0.0%, avg 4ms  |  ok trace: 7 hop(s)  [1/1022]
  10.0.0.2            fail ping: loss 100%          |  fail trace: no route  [2/1022]
  ...

Completed 980 probe(s).
Failed 42 probe(s).
Wrote ping CSV (4088 row(s)) to /current/dir/ping_2026-03-20-...csv
Wrote trace CSV (7154 row(s)) to /current/dir/trace_2026-03-20-...csv

To speed up large runs further, combine with --no-trace (ping only) or --no-ping (trace only).

Operational notes

• pingtrace depends on system ping and traceroute tooling being available on PATH.
• On Windows, tracert is used.
• On Unix-like systems, traceroute is used, with tracepath as a fallback where available.
• --export without a path writes operation-specific CSV files in the current working directory.
• If --export points to a .csv file path, pingtrace uses that file's directory and still writes separate ping_...csv and trace_...csv files.
• Private DNS enrichment is automatically skipped if the configured server does not respond within 5 seconds.
• PeeringDB and ipinfo.io enrichment is skipped for private/RFC-1918 IP addresses.

Feedback

If pingtrace saved you time in a troubleshooting session, it was worth building.

• Star the project on GitHub
• Report bugs or request features in Issues
• Buy a coffee (or a snack for my buddy Schnauzer Tyson) if you feel like it.
