Hi,

I’ve released IPAddress 0.7.0.

> **[GitHub - ipaddress-gem/ipaddress: A library to handle IPv4 and IPv6 addresses...](https://github.com/ipaddress-gem/ipaddress)**
>
> A library to handle IPv4 and IPv6 addresses in a modern and productive way. - GitHub - ipaddress-gem/ipaddress: A library to handle IPv4 and IPv6 addresses in a modern and productive way.

This new release is focused on two points:

- compatibilily with IPAddr

almost all IPAddress methods are compatible with their IPAddr  
counterpart, with the exception of wrong and flawed methods

- performances improvement

IPAddress is now around 50% faster than IPAddr on all normal tasks. As  
an example, this is the speed improvement on initialize and to\_s

```
  user system total real

```

ipaddr 68.960000 20.930000 89.890000 ( 90.105755)  
ipaddress 44.410000 3.880000 48.290000 ( 48.414564)

Some other changes from previous versions:

- Creating a new IPv4 address with no prefix now defaults to /32
- New IPv4::parse\_classful to parse a IPv4 address as classful
- IPv4#private? to check if an IPv4 is private

0.7.0 is not a valid IP address. How did you manage to sneak this by  
the ICANN?

SCNR 🙂

I told them it was the solution for IPv4 address exhaustion 🙂
