Ip Laravel Package

• Rename the whole-value output methods to to* (conversions), keeping get* for component and property accessors. Keep the get* spellings as deprecated aliases; getBinary() is exempt as the accessor of the canonical state.
• Detect embedding strategies via the new Contracts\StrategyDetectionInterface deprecating the old IpInterface::isEmbedded() and associated methods.
• Convert IP addresses to and from integers: fromInteger()/toInteger() via the new Contracts\Factory4Interface (IPv4 and Multi only), plus arbitrary-precision fromIntegerString()/toIntegerString() and fixed-width toHexString() on all classes.
• Add arbitrary-precision base-256 <-> base-10 conversion to Util\Binary: toDecimalString() and fromDecimalString() (GMP fast path when the extension is loaded, backed by pure-PHP fallback).
• Extend Contracts\OutputInterface from \JsonSerializable.
• Expand Contracts\OutputInterface: getOctets(), getSegments(), and canonical toString() (deferable method for Stringable equivalent).
• Add address arithmetic methods next(), previous() and offset(int $offset) to Contracts\ArithmeticInterface. Over/underflowing the address space throws Exception\OverflowException.
• Split embedding strategies into canonical and non-canonical packers via the new Strategy\CanonicalEmbeddingInterface bridge.
• Add strict parsing methods to the new Contracts\FactoryInterface interface: try/from protocol, binary, hex.
• Deprecate factory() in favour of the strict named constructors fromProtocol()/fromBinary().
• Introduce [@experimental](https://github.com/experimental) capability interfaces under Darsyn\IP\Contracts\. Their shape may change before 7.0, but remains backwards compatible for 6.x
• Allow overriding the global formatter per call via an optional Formatter\ProtocolFormatterInterface parameter on toDotAddress(), toCompactedAddress() and toProtocolAppropriateAddress() (deprecated get* aliases accept the same argument, but any other value triggers a deprecation notice and falls back to the global formatter instead of throwing a TypeError).
• Move CIDR mask generation from the protected AbstractIP::generateBinaryMask() to the public static Util\Binary::mask().
• Performance: compute network masks (getNetworkIp() / getBroadcastIp()) and the greatest common CIDR (getCommonCidr()) directly on raw bytes.
• Add arithmetic primitives to Util\Binary: increment(), decrement() and addIntegerOffset(). Over/underflowing throws new exception.
• Widen the $previous constructor argument on all exception classes from ?\Exception to ?\Throwable.
• Add support for PHP 8.5 in README, and GitHub Action CI workflows.
• Access protected method via Closure in unit tests, instead of reflection, to fix deprecation warnings in PHP 8.5.
• Define all data-provider arguments as test method arguments, to fix deprecation warnings in PHPUnit (cherry-picked from 5.0.2).
• Drop all PHP versions except floor (7.4) and latest (8.5) for running static analysis.
• Type-narrow out-of-range CIDRs to remove unnecessary [@phpstan-ignore](https://github.com/phpstan-ignore) instructions.
• Bugfix: don't compress single 16-bit zero group (according to RFC 5952 § 4.2.2).
• Bugfix: stop MbString::subString() from swallowing valid 0.
• Add Bash script for testing GitHub Action workflows locally using Docker.
• Add code style ruleset definition via PHP-CS-Fixer configuration. Apply the code style to the entire codebase, and enable checking as another CI job in GitHub Actions.
• Bugfix: classify full fc00::/7 block as private use.
• Add (or update) community standards: SECURITY.md, CODE_OF_CONDUCT.md and CONTRIBUTING.md
• Bugfix: detect embedded IPv4 across the entire 6to4 block (2002::/16, RFC 3056 § 2), not just canonical 6to4 addresses with a zeroed 80-bit tail.
• Bugfix: align isPublicUse(), isUnicastGlobal() and isDocumentation() with the IANA special-purpose address registries, and update RFC references/citations for all address classification methods.
• Rename isPublicUse() to isGloballyReachable(), conforming to the official wording used in the IANA special-purpose address registries ("Public Use" does not appear in them). Keep isPublicUse() as a deprecated alias.
• Add NAT64 (RFC 6052 § 2.2) embedding strategy, with named constructors for the Well-known Prefix (64:ff9b::/96), operator Network-specific Prefixes, and the RFC 8215 Local-use prefix (64:ff9b:1::/48).
• Add Teredo embedding strategy for 2001::/32 (according to RFC 4380 § 4).
• Add Composite embedding strategy that recognises and extracts version 4 addresses across several underlying strategies, while packing through a single canonical strategy.
• Bugfix: classify a NAT64 Well-known Prefix (64:ff9b::/96, RFC 6052 § 2.1) address by the version 4 address it embeds rather than trusting the prefix, so an embedded non-globally-reachable address is no longer reported as globally reachable (closes a potential SSRF deny-list bypass).

• Rename default branch name from develop/master to 6.x; branch 5.x from 5.0.0 tag for ongoing support (bugfixes only). Update GitHub Actions CI workflows, and update README with description on the 6.x/5.x split.
• Drop support for PHP versions less than 7.1.
• Fix PHP 8.4 deprecation errors (nullable arguments must be explicit).
• Add strict types.
• Add native type support. Remove unnecessary type annotations in doc blocks. Remove unit tests that assert invalid types no longer allowed by PHP's strict typing.

5.0.1 added PHP 8.4 support, but this is deprecated due to true support (without supresing deprecation warnings) being unavailable without lifting the minimum PHP version (5.6).

PHP 8.4 is now only supported (officially) on 6.x.

• Officially deprecate PHP 8.4 support for the 5.x branch. Highest PHP version supported for 5.x is 8.3, upgrade to 6.x for higher PHP versions.
• Update version requirements in README, composer.json and GitHub Action CI workflows.
• Define all data-provider arguments as test method arguments, to fix deprecation warnings in PHPUnit.
• Remove [@phpstan-ignore](https://github.com/phpstan-ignore) instruction for non-issue in unit tests.

• Add support for PHP 8.4.
• Reference comment added for generating documentation on Podman.

• Removed Doctrine functionality, and split it off into its own package: darsyn/ip-doctrine. List it as a Composer dependency suggestion.
• Change from Psalm to PHPStan for static analysis.
  • Add types to all function arguments lists and return values.
  • Update the codebase to pass static analysis on max level (standard, deprecation, and bleeding edge rules).
• Test against PHP versions 8.2 and 8.3 in CI pipeline.
• Update README with notes on version compatibility.
• Explicitly state the requirement of the ctype PHP extension.
• Add PHPUnit attributes alongside annotations to be compatible with the highest version of PHPUnit for any supported PHP version.

• Added IpInterface::equals() method for comparing two IP addresses.
• Added getCommonCidr(IpInterface $ip): int for determining how in range two IP addresses are according to their common CIDR value.
• Added isBenchmarking(), isDocumentation(), and isPublicUse() type methods for both IPv4 and IPv6 addresses.
• Added isBroadcast(), isShared(), and isFutureReserved() type methods for IPv4 addresses.
• Added getMulticastScope(), isUniqueLocal(), isUnicast(), and isUnicastGlobal() type methods for IPv6 addresses.
• Added Ipv6::fromEmbedded() factory method to create an instance of an IPv4-embedded address as IPv6 instead of Multi.
• Made internal helper methods for dealing with binary data into utility classes: Darsyn\IP\Util\Binary and Darsyn\IP\Util\MbString.
• Complete documentation overhaul
• Increase test coverage.
• Started using static analysis both locally and via GitHub actions.
• Documentation and tests are excluded from the Git archive to reduce download size when installing Composer dependency as dist.
• Updated Code of Conduct to Contributor Covenant v2.1

• Add return types to DocComments to prevent symfony/error-handler from throwing deprecation errors

• Add Code of Conduct to project.
• Add new internal helper for dealing with binary strings.
• Add namespace indicator to function calls to speed up symbol resolution.
• Add __toString() to IP objects.
• Update unit tests, now runnable on all PHP versions 5.6 to 8.1

• Complete rewrite of library.
