FWIW, I took a look at my scans data and there's a lot of this around. Of
the 5477 PTRs with spaces, in approximately ~490 domains*, those with more
than twenty hosts with PTRs containing spaces are the following:
\032 is space. Go read STD13 aka RFC 1034 and RFC 1035.

In DNS zone files (and dig's presentation format) backslashed numbers
are in decimal, not octal - RFC 1035, §5.1.

So, someone trying to "undo" in a GUI editor, or a failed attempt to exit 'vi'?
Cheers,

Owen,
Ah, so a cross-base typo! :)

\032 is not a space.
Decimal 32 (0x20, \040) is a space.
\032 is a Ctrl-Z (26 decimal, 0x1a)

Typo I’d say. DB-drive DNS servers, which don’t keep their entries in
traditional PTR-record text format, can fall victim to this. Rather than parse
the text every times, they just spit out whatever is in the table column, even
if it has embedded spaces. I’ve seen this happen in SnitchDNS.
