The patch applied for removed the block from the reserved list. 

RFC 6890 [] calls out as a "Reserved" block. Bug mistakenly claimed that RFC 6890 does not list this as a reserved block. You will find it on page 12 of that RFC.

Test script:

Expected result:

Actual result:
string(9) ""

No, nonsense. is reserved, but is not
reserved. Therefore the behavior of your test script is expected.

I apologize for mixing up those ranges.

Nevertheless, the range is reserved for multicast.

"The range of addresses between and, inclusive,
is reserved for the use of routing protocols and other low-level
topology discovery or maintenance protocols, such as gateway discovery
and group membership reporting.  Multicast routers should not forward
any multicast datagram with destination addresses in this range,
regardless of its TTL."
