Can Faker generate IPv6 addresses with different formats

Generating a Standard IPv6 Address

To generate a standard IPv6 address, you can use the `ipv6()` method:

php
$ipv6Address = $faker->ipv6();
echo $ipv6Address; // Outputs a random IPv6 address, e.g., '2001:0db8:85a3:0000:0000:8a2e:0370:7334'

Generating a Compressed IPv6 Address

Faker also allows you to generate compressed IPv6 addresses, where leading zeros are omitted and consecutive blocks of zeros are replaced with a double colon (::):

php
$compressedIpv6 = $faker->ipv6('compressed');
echo $compressedIpv6; // Outputs a compressed IPv6 address, e.g., '2001:db8:85a3::8a2e:370:7334'

Generating a Netmask IPv6 Address

You can generate an IPv6 address with a netmask by passing the `'netmask'` option:

php
$netmaskIpv6 = $faker->ipv6('netmask');
echo $netmaskIpv6; // Outputs an IPv6 address with a netmask, e.g., '2001:db8:85a3:0:0:8a2e:370:0/64'

In this example, the generated address includes a netmask with a prefix length of 64 bits.

These methods allow you to generate IPv6 addresses in different formats, depending on your specific requirements. The `ipv6()` method generates a standard IPv6 address, while the `'compressed'` and `'netmask'` options provide variations to suit different use cases.
