Title:
ipv6 subnet reserves 2 addresses in allocation pool
Status in neutron:
Expired
Bug description:
consider this table:
125::/125 | {"start": "125::1", "end": "125::6"} |
126::/126 | {"start": "126::1", "end": "126::2"} |
127::/127 |
|
128::/128 |
|
all those subnets created with
neutron subnet-create --ip_version 6 --disable-dhcp --no-gateway NETWORK CIDR
You see that ::0 and the largest address in CIDR are reserved.
This is similar to ipv4 where we have network address and broadcast address,
while
according to
http://www.iana.org/assignments/ipv6-interface-ids/ipv6-interface-ids.xhtml
there should be no this reservation for ipv6.
Situation for prefixes 127 and 128 even worse, no addresses at all.
