'Owning' IP addresses - good or bad idea?
-
We're about to acquire a company which has a very small block (/29) of IP addresses registered to their company by ARIN. Aside from the obvious benefit of never having to change/give up those addresses in the future, what are the pros/cons of being registered with ARIN and 'owning' IP space? Clearly we don't currently own any IPs, just get what our ISP gives us through our static /28.

If you have your own AS, you can do provider-independent routing with BGP, so you aren't tied down to a single upstream.

In general that's the reason. Though probably not with just a /29, anything smaller than a /24 is highly unlikely to make it in the global BGP routing table as many providers will filter out smaller routes than that.
