Allocation vs assignment question
Hello all, I have posted similar question at https://www.ripe.net/ripe/maillists/archives/db-help/2006/msg00040.html but I think that was not appropriate list, and I'm still not sure which is. My question is am I correct in assuming that all "assigned" IPs are on same physical network that all other IPs in their "sub-allocation" range? For example, here inetnum: 217.77.240.0 - 217.77.255.255 org: ORG-SW1-RIPE netname: DE-SAP-20001221 descr: SAP-AG Walldorf descr: ENTERPRISE country: DE status: ALLOCATED PA inetnum: 217.77.254.28 - 217.77.254.28 netname: SAP-JCrewGroupInc-US-i8 descr: J. Crew Group Inc. descr: US 770 Broadway, 14th Floor descr: Remote connection to SAP country: US status: ASSIGNED PA inetnum: 217.77.254.30 - 217.77.254.30 netname: SAP-AlumaFormDixieElectrical-US-i8 descr: Aluma-Form/Dixie Electrical descr: US 3625 Old Getwell Road descr: Remote connection to SAP country: US status: ASSIGNED PA are 217.77.254.28 and 217.77.254.30 still on german network, or are they physically located in US and connected to germany over some sort of intercontinental cable? Thanks, Max.

So, if you have IP range A.B.C.* allocated to you, and assigns A.B.C.D to someone else, A.B.C.D may be plugged in any switch on the internet, not necessary yours?

That's not what I said (and is a different conclusion from the original question). First, the entry in the RIPE Database does not necessary correlate to a physical "subnet" in the sense of "all these IP addresses are in a single LAN". Most of the time, this is not going to be the case - like "a company getting assigned a network of a given size, and using subnets out of that network for different purposes, like branch offices". Second, of course you need to make sure *routing* for the address ("A.B.C.D") works - so if you plug it in "anywhere", it will not work. Still, A.B.C.D *could* be "anywhere" - depending on the specific layout of the network in question. They could use A.B.C.* for VPN connections, and route the individual addresses via IPSEC tunnels to "anywhere". Summary: you cannot draw any definite conclusion about physical or geographic setup from the RIPE (or any other) database.

Hi, In general, yes. Really it can work in some cases.Even without ask for your permission ;) Makc The Great wrote:
