> hint: this affects the GLOBAL routing tables
Let's look at this practically.
ZA is presently announcing approximately 650 prefixes. If you include the
rest of Africa that falls within the ARIN allocation region, this would
still be less than 1000 prefixes. Given that a global routing table is
approximately 120'000 prefixes, we're talking about less than 1% of the
table.
Even if the number of ISPs in Africa receiving address space from ARIN were
to double, this would have an impact of under 1% of the table. (Remember,
not all of the ~1'000 prefixes are ARIN assignments...many - if not most -
are from upstreams and pre-ARIN).
There are only 19 ARIN members in Africa. If this figure were to quadruple,
that may mean another 57 new prefixes to be announced... 0.05% of the total
routing table.
This affects the global routing tables in the same way that a butterfly
affects wind currents.
