How does one obtain a block of IP addresses? I need about 100 public addresses, but not sure how to obtain these. It would seem that I would need to subscribe to an enterprise connectivity to a Provider and then purchase IP's from them? Sound about right? Problem is those connectivity options are horrendously expensive via Telkom/Neotel. What other options exist?
 
Well to use public IP's it is best to use connectivity such as fibre, wireless etc. Over ADSL you would need to tunnel to the ISP to get those public ips, not ideal.
Using fibre/wireless you could then purchase a /25 or such range of IP's from your ISP/Datacenter that you are connecting too. Alternatively you could register your own ASN and apply for a /24 from afrinic.
 
The amount of public IP's you get = dependent on how much you pay your ISP or how much they like you.
You can always ask them for more public IP's but you'll need to motivate why you need so many + hope they have the IP's to give.
Normally a requirement for hundreds of public IP's is the result of poor planning. (no disrespect :-) )

The norm is to run NAT. (network address translation)
You enclose all your resources (servers, PC's & whatnot) inside a private network.
One or more routers connect the private network to the public (Internet) network.

Each router needs minimum of 1 public IP and the router then routes packets between the private & public networks.
That way, you use very few public IP's while having hundreds/thousands of private IP's inside your private network.

The more users/traffic you have = the bigger (more expensive) your router requirement.
+ you can have 2 or more routers for redundancy & speed (web browsing goes via one router and VPN + email via another for instance)


If you don't run Cisco VPN and need lots of bandwidth with a couple of public IP's look at line bonding.
Maybe go for 4 or more 4Meg ADSL lines bonded together to form one virtual (very fast) link.
Latency and throughput on a bonded ADSL link is exactly the same as on a Telkom leased line, (just MUCH cheaper)


Sadly Telkom won't fix your ADSL issues as fats they fix diginet issues so best is to have a 128Kb diginet as a backup.
Both diginet & bonded link goes into a Cisco 1841 or 1941 router which then does automatic fail-over if the primary link does.

Thanks, for the info guys.

The servers will live inside my network on private addresses, the public is for customers to get to the natted addresses on the inside.

I was looking at getting a Wimax Connection with Neotel, but they only come with 5 public addresses and unfortunately I need a bit more than that which they will not provide, hence i'm looking for alternatives.
 
Maybe chat with a couple of ISP's and see what they can offer you.
MTN Business is good and they'll probably be able to give you a whole handful of IP's but it'll be at a price.

What is the function of these servers? I am sure you could use published services to drastically minimize the amount of IP addresses you need
 
Indeed. Get a ASN, then get your own IPs, Ask for a 2bit ASN if you can still get one, some ISPs dont accept the new 4bit ASNs yet.

Then once you have an ASN, something like 36999 you get a /24 something like 196.43.215.0/24, then your options open up. You can use those even on diginet, just tell the provider you want to announce it to them. I am pretty sure Neotel, Telkom, IS and MTNbusiness will all accept it.
