@sideway/address is a robust library designed for parsing and validating IP addresses and domain names. It provides a comprehensive set of utilities for handling various address formats, making it a valuable tool for developers working with network-related applications. The library is particularly useful for ensuring that input addresses conform to expected formats, which can help prevent errors and improve data integrity.

While @sideway/address offers a solid solution for address handling, there are several alternatives in the ecosystem that provide similar functionalities. Here are a few noteworthy options:

• @hapi/address is a fork of the original address library, maintained by the Hapi.js team. It provides similar functionality to @sideway/address, focusing on parsing and validating IP addresses and domain names. Developers who are already using the Hapi ecosystem may find this library particularly appealing due to its integration with other Hapi tools and its commitment to maintaining a high standard of quality and performance.

• address is another library that focuses on parsing and validating IP addresses and domain names. It is lightweight and straightforward, making it easy to integrate into various projects. While it may not have all the advanced features of @sideway/address, it serves as a solid choice for developers looking for a simple solution for address handling.

• geoip-lite is a library that provides geolocation capabilities based on IP addresses. While its primary focus is on determining the geographical location of an IP address, it also includes features for parsing and validating IP addresses. If your application requires geolocation functionality alongside address validation, geoip-lite is a great option.

• ip6 is a specialized library for working with IPv6 addresses. It provides utilities for parsing, validating, and manipulating IPv6 addresses, making it an excellent choice for applications that need to handle the complexities of IPv6 networking. If your project specifically targets IPv6, this library can simplify many of the challenges associated with it.
