Sigh,

Before we get into a flame on the list, I wish people would check their
facts and RTFM the RFCs. Haymee should have minimal problems with a second
link through a second upstream provider with the 194.133.121.0/24 prefix.

Fact - the allocation for EBOnet is 194.133.121.0

Fact - this is an non-contiguous full allocation from RIPE-NCC
(whois.ripe.net):

inetnum:     194.133.121.0 - 194.133.121.255
netname:     ANGOLANET
descr:       Rua Conselheiro J Bilhena no 7
descr:       Luanda
descr:       Angola
country:     AO
admin-c:     AC267-RIPE
tech-c:      AC267-RIPE
status:      ASSIGNED PA
changed:     [log in to unmask] 19980916
source:      RIPE

person:      Anibal Cordeiro
address:     Rua Conselheiro J Bilhena no 7
address:     Luanda
address:     Angola
phone:       +244 2 330281
fax-no:      +244 2 397189
nic-hdl:     AC267-RIPE
changed:     [log in to unmask] 19961024
source:      RIPE

This means that EBOnet can advertise out which ever link they wish. How do
we know this? See below.....

Fact - the orginal allocation cam from GlobalOne. This can be seen by the
source site of Anibal Cordeiro - www.si.net.

Fact - 194.133.121.0 is currently being advertised out of UUNET/Worldcom. We
know this by a traceroute from my home to www.ebonet.net (see below).

Conclusion: Even if the block originally was allocated from GlobalOne and is
still managed by GlobalOne, GlobalOne is not stopping this advertisement out
to the internet (primarily because it is not part of a GlobalOne
superblock).

Recommendation: First - Join RIPE-NCC and/or AFRINIC. This will allow the
current block's custodian to be changed from Anibal Cordeiro to someone in
EBONet. Second, get a new IP address allocation for the IP Registry (need to
be a member).


Note1: What Eberhard W Lisse [[log in to unmask]] said is true - if you get a
block of addresses from your upstream ISP's superblock. Hence, it is
recommended that ALL ISPs be a member of a IP registry (ARIN, RIPE-NCC,
APNIC, and now AFRINIC). That way they do not have to worry about
renumbering their entire network (and all their customers) when they move
from one provider to the other. This is policy is defined in RFC-2050 and
finer policy decisions in each IP registry (see their web sites for the
details).

Note2: The use of "private" IP address space is encouraged. RFC-1918
highlights the use of these private address space. DHCP and NAT are both
tools where corporate networks can have flexible IP address plans - IP
address plans that can easily be changed when moving from one ISP to
another.

Personally, I never recommend NAT for ISPs. There are plenty of IPv4
addresses yet to be allocated. The allocation policies are working -
conserving IPv4 address space. Hence, there is plenty of space for new ISPs.
ISPs need to include a registry membership fee as part of their business
plan - allowing them to get their own allocations.

Report for www.ebonet.net [194.133.121.8]

Analysis: Node 'www.ebonet.net' was found in 22 hops (TTL=43). But, problems
starting at hop 20 in network "UUNET Technologies, Inc." are causing IP
packets to be
dropped. It is a HTTP server (running Apache/1.3.3 (Unix)).
