Did You Know? Groundnut Pyramid
Several years back, local Nigerian companies commenced exporting groundnuts, cashew nuts, sesame seeds, moringa seeds, Ginger, cocoa etc
Groundnut pyramids were the invention of Alhassan Dantata, a prominent nut trader.
Dantata came to Kano in 1919 and within five years was one of the most successful businessmen, supplying the Royal Niger Company (RNC) with most of their groundnuts. Dantata’s company kept their groundnuts at a facility in Kofar Nassarawa, and they stacked the bags in the shape of a pyramid before they were shipped.
One groundnut pyramid could be made from as much as 15,000 full groundnut bags. A journalist who visited a former groundnut pyramid site in Kano reported that the land was now a football field.
Groundnut pyramids were built all across northern Nigeria, in cities like Kofar Mazugal, Brigade, Bebeji, Malam Madori and Dawakin Kudu. The pyramids became synonymous with Nigeria’s agriculture wealth; a postage stamp even featured a groundnut pyramid. However, as groundnut production declined in the 1970s and 80s the groundnut pyramids disappeared and were replaced with buildings.

You was never intended to use IPv4 addresses and certainly not IPv4The link local IPv6 address are nothing like the private IPv4 addressesAnd if you want to access your server, then give it a easy IPv6 static address and put that in your DNS server Or use mDNS, like it is meant to be used Then you can use the same name when you reach your machine with IPv4 or IPv6 addresses Yes, every interface used to get accessed from internet or access internet will get multiple IPv6 addresses– First is the fe80::/64 address which is the link local address This IPv6 address will be used when accessed from another/same machine on the same link/LAN Without this one, IPv6 will not work So this is the only one that must exist That you can’t turn off– Second if you have a router in the LAN; you could get an public IPv6 address in the IPv6 net 2000::/3, that is starts with a digit 2 or 3 That one will use the LAN prefix (which always is a /64 network) that it gets from the router and make a public IPv6 address based on the MAC address, which generate the lowed 64 bit of the 128 bit IPv6 addressThe second can also be generated from the network address but the host part be randomized instead of from the MAC address This can be configured on your machine, and can be turned on so it automatically get the right public IPv6 addressThe middle of the host part will always be FF:FE and have a high bit set– Then you can set up, if you want to configure that, so outgoing traffic generate a temporary global address that is used in 5 minutes (or so) then generated a new one And as long as there are package that could return for that address, that older address will still be there So if you surf a lot, you can have several of these temporary addresses Used so that web sites should not be able to trace your machine when it access the web site You can turn this one off– Then you can, if you want to, set a public address that can be set up to be used when you access the server, but not surfing the internet from the server That is just intended to be used to access this machine, so it is usually added to an external DNS server So other can reach this server through this address Usually you only have one, but you can use several static ones One for each service you set up Might be useful if you set up server on that machines But his has to be manually set And if you see to that the middle of the host part is 00:00, then it never will mix up with the automatically generated addressesNot that hard, isn’t it?You only use the static address if you want to add that into a DNS Except from that, you use the machine name in DNS or in the link local mDNS OR you use the static address that you created, if you make it easy to remember You never uses the FE80::/64 address you mentioned when accessing one IPv6 machine Not on internet nor in your LAN
