Hello!
Currently I am working on bug #74699 (Thanks brianlmoon for pointing this issue).

Here is some details:
In patch applied for bug #72972 IP address block 240.0.0.0/4 has been removed from list of reserved.

But according to IP Multicast Address Specification:
“The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive,
is reserved for the use of routing protocols and other low-leveltopology discovery or maintenance protocols, 
such as gateway discoveryand group membership reporting.  
Multicast routers should not forwardany multicast datagram with destination addresses in this range,regardless of its TTL.”

Here is the full specification: 
https://www.iana.org/assignments/multicast-addresses/multicast-addresses.xhtml

That’s why my PR introducing changes to include addresses between 224.0.0.0 and 224.0.0.255 in list of reserved.
Here is link to my PR
https://github.com/php/php-src/pull/2562

Thanks!

Any updates on this? Does it look like reasonable change?

I'm bumping this message as I believe that a lot of people are not receiving Andrew's emails due to his email configuration being borked, and the issues seems like something that should be resolved. cheers Dan
