A domain query method allows the instance to efficiently query large numbers of domains.
Part of Domain Support 2.0 is a new query engine designed to perform and scale to tens of
thousands of domains. Prior methods, including domain numbering, have had limitations that domain
paths resolves. While you have the flexibility to continue using your existing query method, we
highly recommend that you switch to domain paths through the new Domain Configuration screen at
your earliest convenience.
A domain path is a series of three-character codes separated by a slash (/) delimiter that
uniquely identifies a domain. Each digit in the three-character code consists of one of the
following 60 possible characters:
The three-character codes that make up a path are not unique across a domain tree. Rather, the
entire path string itself is unique. For example:

Note: With three-character codes delimited by a single character in a path string of 255 total
characters, each node of the domain tree supports up to 216,000 child domains, and the maximum
depth of the tree is 63 levels.
