How many External Fixed IP's

[ict_support]

We are in the process of changing ISP's in the school role (large secondary) and the new ISP is asking how many fixed IP's we would like. What are peoples thoughts on this

How many fixed IPs do you need?

[powdarrmonkey]

V4 IPs are a scarce resource. You have to be able to justify their use to RIPE; ergo, don't be greedy just because you think you might 'need' them in the future. The rules forbid this.

normally they come in blocks of 5 or 8 usable IPs, how much stuff do you host internally?

We were given 8 with ours, just in the process of using them when I get my UAG up and running.

 

I think 2 are set aside so we get 6 to use.

we host internally an mis system, moodle, owa/exchange, however just because we have external access to these systems does not mean that each one would need a seperate external IP...

What do you use them all for?

[k-strider]

I would ask for a block of 16 this gives you 14/3 usable adresses, i did manage to justify this at home for personal use! but if you get a block of 8 remember thats only 6 usable but one of the useables will be your router. so 5 others... if you have more than 5 ssl servers that requier outside access that would probably be enough to justify it...

When we changed ISP last year we had to complete quite a bit of extra paper work to describe what each IP would be used for because as someone has mentioned above they are in short supply at the moment. So had to prove why we needed that many and as stated above the old "we might need them for X and Y in the future" wasnt allowed.

Would it sound like boasting if I said we had 4 complete class B networks (something over 265,000) and it never seems to be enough?

[localzuk]

We have 2 for our school. One for the main website, and a second one for various other services such as RDP, an SSL API for an external site etc...

 

Don't think we'd need any more to be honest! We can quite happily host everything we need on those 2, using different ports and reverse proxying for http stuff.

Almost all of our sites have to get by with one as that is all that our DSL technology supports (thanks again Telecom NZ for providing the worst systems in the known world)

Definitely sounds like boasting! That's why we are rolling out IPv6, or it may be because networks need some new toys?
