It's got to be PA space. Paetec isn't in a position to assign PI space.
No distinction is drawn between PA and PI for ARIN-region address space assigned prior to ARIN's inception in 1997. That's "legacy" address space. Since the end of filtering on prefixes shorter than /24, PA and PI have lost most of ther distinction anyway. There's RIR-assigned and there's LIR assigned. The RIR assignes addresses to LIRs and end users. The LIR assigns addresses to LIRs and end users. Unless its IPv6 in which LIRs are strongly discouraged from assigning addresses to other LIRs and multihomed end users. Short version: drop PI and PA from the conversation. It makes absolutely no difference whether the customer thought Paetec assigned them PI space. The customer's addresses are either directly from ARIN or they're from Paetec. That's it. If the latter, it's up to Paetec what the customer can and can't continue to do with them. Regards, Bill Herrin -- William D.
