It is accessible, and small teams lease space all the time. You do not need LIR membership to lease, that is one of the main reasons small companies go that route. What you do need is an upstream willing to accept the LOA and announce for you, so confirm that with your transit provider before you sign anything. Block sizes usually start at a /24, which is plenty for three engineers. We started the same way, leasing IPv4 , from InterLIR Global before we had any real infrastructure. Honest caveat: for proxy workloads, ask specifically about the range’s reputation history, because inherited blocklist entries will ruin your week.
