How much should an LIR be charging for requesting IP space on my
behalf?
IP addresses are a public resource and should not be bought or
sold. It is reasonable, however, for an LIR to charge a fee for
administering the address space that they assign to you. The RIPE
NCC has not stipulated a charging schedule. This is left to the
discretion of the membership.
Further information on the RIPE community's policy on charging by
LIRs can be found in the RIPE document "Charging by Local Internet
Registries" found at:
http://www.ripe.net/ripe/docs/chargingbylirs.html
"Thus, while registries may charge for their administrative and
technical services, they may not charge for name space or address
space as such; no unit cost or price tag can be attached to a
domain name or to an IP address, public or private."
