Which network is assigned address physically on?

Hello all.

My question is which network is assigned address physically on?

According to http://www.ripe.net/ripe/docs/ipv4-policies.html, "an
allocation is a block of IPv4 addresses from which assignments are
taken... Sub-allocations are intended to aid the goal of routing
aggregation... The minimum size of a sub-allocation is /24. This is
the smallest prefix length that can be reverse delegated and allows
for a reasonable number of small assignments to be made by a
downstream network operator... The maximum size of a sub-allocation is
/20 even if this is less than 400% of the LIR's AW (Local Internet
Registries' Address Window). For example, an LIR with a /21 AW may not
sub-allocate a /19 to a downstream network. However, downstream
network operators may receive sub-allocations totalling more than a
/20 from more than one LIR."

I am too stupid to figure out what does it mean. Let's take an example:

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

Does it mean 217.77.254.28 and 217.77.254.30 are still on german
network, or are they physically located in US and connected to germany
over some sort of intercontinental cable?
