An assignment refers to the range of IP addresses that an AFRINIC member will use from allocation given by AFRINIC for the following purpose:-
- An end-site or customer with 4 or more IP addresses
- A subnet for the organisation's own network infrastructure
- Any range from which IPs are dynamically assigned
PA space is what has been allocated to LIRs from which they can assign or sub-allocate to end-users / downstream networks as non-portable block. If the end-user / downstream network changes provider, the address space assigned or sub-allocated by the previous service provider (LIR) should be returned and the network renumbered.
Provider-Independent (PI) addresses are globally-unique addresses which :-
- are not assigned by a transit provider
- cannot be aggregated
- can only be assigned by a Regional Internet Registry(RIR)
- cannot be sub-allocated to another entity
A sub-allocation is a block of IP address space given by an LIR to ISPs (LIR's customers) for the purpose of subsequent distribution.
Reverse delegation is reverse DNS record which map an IP address to a name. It is usually maintained by the organisation who receives direct allocations from an RIR. Reverse delegation is achieved by use of the special domain names in-addr.arpa (IPv4) and ip6.arpa (IPv6). It is usually used to validate a forward DNS record, make network troubleshooting more user friendly by providing names instead of IP addresses and also as part of e-mail anti-spam best practices.
Route object is an object created in Internet Routing Registry to specify the Autonomus System Number "ASN" that will propagate this exact IP prefix to Internet. It can also be used to give information about the organisation that advertises this prefix. Route objects are usually protected and only a person with the authorised password can change them.
Route objects are usually used by Internet Service Providers and Upstreams to validate that routes received from their peers are legitimate. This usually help eliminate routes hijacking if used by all providers. They don't eliminate the need for BGP configuration and advertisement.
Two methods are available – via the myafrinic portal or by updating the whois database using the email method.
a) Updates via the myafrinic portal can be done as follows:-
Log into https://my.afrinic.net
Go to Resources -> IPv4 Resources
Click on "+" to expand on the target allocation
Click "Add Assignment"
You need to repeat the above process for all assignments that will be registered. Any changes you make from MyAFRINIC will be instantly updated in the AFRINIC Whois database.
b) Update of assignments on the whois database by email
It is possible to send one batch job in one email (containing multiple assignments) using the procedure listed here
We recommend that you add the sub-allocation via the myafrinic portal.
You may do this via https://my.afrinic.net as follows:
o Log into https://my.afrinic.net
o Go to Resources -> IPv4 Resources
o Click on "+" to expand on the target allocation
o Click "Add Sub-Allocation"
o Fill in the form and submit
The AFRINIC hostmasters will then revert back to you for evaluation of the request.
An LIR may receive an additional allocation when about 80% of all the address space currently allocated to it has been used in valid assignments and/or sub-allocations. A new allocation can also be made if single assignment or sub-allocation requires more addresses than those currently held by the LIR.
