- With the test from outside, the route from the publisher's server back to your address
came back empty: the trace program holds its output until it ends, and it was stopped
first while waiting on routers that never answer. It now reports each router as soon as it
answers and stops after three silent ones, so the routers in front of your provider's exit
reach the app.

- Behind your provider's shared address, me-web? now shows how its exit hands out ports
(kept, one after another, from one block, or at random), the range it gave this device,
and how many customers may share the address at most; the estimate sharpens with each
check on the same address.
- It tests whether two devices behind the same address can reach each other (hairpin), and
how long an unused connection stays open: the card says "measuring" for about two minutes
after the check, then the answer.
- With the test from outside, the publisher's server also traces the route back to your
address: your provider's routers and the networks in between appear on the path, with
their names.
- The provider card says which networks your provider reaches the internet through.
- On mobile data, the path shows the operator and the type of network (5G, 4G) read from the
phone; on Android 13 and later the phone asks once for permission to read the network type.
- The speed card adds the round trip to the publisher's server.
- The network data now comes from the publisher's server, refreshed there from open sources:
iptoasn.com, DB-IP Lite (CC BY 4.0), the University of Oregon Route Views Project (CC BY 4.0)
and the Android Open Source Project's list of mobile operators (Apache 2.0); the release
notes list each source's date and checksum.
- Source links in the cards wrap instead of being cut off.
- New strings, drafted in every language.

Phases two and three ship together, because their code grew in the same
files. With consent the app asks the router to open 80, 443 and a high
port for ten minutes (UPnP, NAT-PMP or PCP), and the server, holding a
single-use ticket bound to the caller's own address, connects back and
must get an HMAC only the app can give; the mappings are removed after the
run and remembered until then, so a crash cannot leave one open. Hairpin
is tried from inside. Two STUN servers, the outside one first, tell easy
from hard NAT.
Mail gets port 25 to Gmail and Outlook, the reverse name and five
blocklists through the user's own resolver, network-wide UCEPROTECT
listings counted as a caution. DNS, speed against the server (four at a
time, twelve an hour per address) and the device follow, and six uses
(website, home from outside, files, game server, fediverse, mail) close
the run as possible, possible with a named workaround, or can't tell.
Findings can be shared after reading the exact JSON: a file per submission
under the unit's state directory, ten a day per address, deletable by the
token the app keeps, swept after twelve months; /privacy says all of it in
English and Italian. QR codes lead to the downloads. Every language carries
every string.
