Where 5353 fits
Why 5353 is special
mDNS is why a printer, speaker or TV appears by name on a home network with nothing configured. Devices answer name queries about themselves, which works well on a trusted network and leaks a device inventory on an untrusted one.

5 × 1,000 + 3 × 100 + 5 × 10 + 3 × 1 = 5,353. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

The IEEE 802 family defines the wired and wireless networks that multicast DNS runs over to let devices find each other without any server.

mDNS lets a network resolve names without a DNS server: each device answers for itself. That is why .local addresses work on a home network and why an untrusted network learns the make, model and hostname of everything on it.
