program shutdown, and are read in at startup.
Subnet matching for the purpose of access control is now done
by matching the binary network address, instead of with string wildcard matching.
For the user this means that `-rpcallowip` takes a subnet specification, which can be
- a single IP address (e.g. `1.2.3.4` or `fe80::0012:3456:789a:bcde`)
- a network/CIDR (e.g. `1.2.3.0/24` or `fe80::0000/64`)
- a network/netmask (e.g. `1.2.3.4/255.255.255.0` or `fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`)
An arbitrary number of `-rpcallow` arguments can be given. An incoming connection will be accepted if its origin address
matches one of them.
For example:
| 0.9.x and before | 0.10.x |
|--------------------------------------------|---------------------------------------|
| `-rpcallowip=192.168.1.1` | `-rpcallowip=192.168.1.1` (unchanged) |
| `-rpcallowip=192.168.1.*` | `-rpcallowip=192.168.1.0/24` |
| `-rpcallowip=192.168.*` | `-rpcallowip=192.168.0.0/16` |
| `-rpcallowip=*` (dangerous!) | `-rpcallowip=::/0` |
Using wildcards will result in the rule being rejected with the following error in debug.log:
Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24).
