--verbose or -v : makes the program more talkative

--help or -h : this message

--displayprobes or -o : display the probes numbers (WARNING: big lists)

--displayprobeasns : display the (unique) probe ASNumbers (currently only for blaeu-resolve)

--cache-probes= <file.json> : cache probe data

--country = 2LETTERSCODE or -c 2LETTERSCODE : limits the measurements to one country (default is world-wide)

--area = AREACODE or -a AREACODE : limits the measurements to one area such as North-Central (default is world-wide)

--asn = ASnumber or -n ASnumber : limits the measurements to one AS (default is all ASes)

--prefix = IPprefix or -f IPprefix : limits the measurements to one IP prefix (default is all prefixes) WARNING: it must be an *exact* prefix in the global routing table

--probes = N or -s N : selects the probes by giving explicit ID (one ID or a comma-separated list)

--requested = N or -r N : requests N probes (default is 5)

--percentage = X or -p X : stops the program as soon as X % of the probes reported a result (default is 90 %)

--measurement-ID = N or -m N : do not start a measurement, just analyze a former one

--old-measurement MSMID or -g MSMID : uses the probes of measurement MSMID

--include TAGS or -i TAGS : limits the measurements to probes with these tags (a comma-separated list)

--exclude TAGS or -e TAGS : excludes from measurements the probes with these tags (a comma-separated list)

--port = N or -t N : destination port for TCP (default is 80)

--size = N or -z N : number of bytes in the packet (default is 64 bytes)

--ipv4 or -4 : uses IPv4 (default is IPv6, except if the parameter or option is an IP address, then it is automatically found)

--tags TAGS : tag the measurement (no relationship with probes tags) (a comma-separated list)

--spread or -w : spreads the tests (add a delay before the tests)

--private : makes the measurement private

--resolve-on-probe : resolve names with the probe’s DNS resolver

--machine-readable or -b : machine-readable output, to be consumed by tools like grep or cut

--format or -k : downloads the results and format them in a traditional traceroute way

--simpleformat : the same, but without looking up the AS (useful if you have no whois access)

--protocol = PROTO or -j PROTO : uses this protocol (UDP, TCP or ICMP, default is UDP)

--do_lookup or -d : Enables IP lookup feature (default is disabled, may become interactive if the machine has several addresses)

--do_reverse_lookup or -l : Enables reverse IP lookup feature for hops
