Or, if the provider isn’t stingy a /48 from the providers /≤32 (providers can get as many /48s as they need to support whatever number of customers receiving them, at least in the ARIN region). > A rule of thumb I go by in the datacenter is, a /48 per customer per site, > and further splitting it into /64s per VLAN, all of which can be plugged into > a spreadsheet formula to produce a valid complete subnet. > > Either way, keeping track of IPAM via spreadsheet is a recipe for disaster. > NetBox and Nautobot are my choices, and is worth deploying on a server or > VPS, even for home labs.
