Buying IP addresses has drastically changed over the past 7 years. While there were minimal options when IPv4 was first exhausted in 2015, the IPv4 landscape has matured with more sophisticated systems and better support from organizations. Due to the limited information available today, we created a comparison of PrefixBroker’s model, vs a more supportive direct buying option with Brander Group’s IPv4 Connect. We offer a more supportive direct buying option, which includes IPv4 blacklist reporting, secure payments, Buy-Now options, published prices, and pre-approval assistance.
