Curious how long you've been sitting on the IP block. I've been nosing around getting an ASN to mess around with the lower level internet bones but a /24 is just way too expensive these days. Even justifying an ASN is hard, since the minimum cost is $275/year through ARIN.
Is that the minimum for an ASN? /24 is a lot of public IP space! I'd expect just to get a static IP from and ISP if I were to coloc like this
