1701
Port 1701 carries L2TP, and NCC-1701 is the registry of the USS Enterprise.

Where 1701 fits
Why 1701 is special
Both are real and neither derives from the other. L2TP tunnels traffic but provides no encryption itself, so it is almost always paired with IPsec — a combination written L2TP/IPsec precisely because the first half is not enough alone.
Same number, different meanings
How 1701 is understood across different contexts — never implying one meaning because of another.

- Technology & computing
In 1701, Jethro Tull developed the seed drill, an early step in agricultural mechanisation (England).
- Media & popular culture
NCC-1701 is the USS Enterprise's hull registry, and the digits alone are recognised well beyond people who watch the programme. Its designer said he chose 1701 to be unmistakable on screen at low resolution, which is an unusually practical origin for a piece of fiction.

28 × 60 + 21 = 1701. Places are separated by a space on the tablet, with the higher place written first.
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.

Related numbers & connections
1701 is a year in the 18th century, in the 1700s.
L2TP provides a tunnel with no encryption of its own, so it is deployed as L2TP/IPsec. OpenVPN bundles both functions, which is why it needs only one port.
