IP Addresses - Can I Get Additional IPs? - People Telecom Forum
Swiftel can provide additional blocks of IP addresses for those users who need them.
The charges for these blocks of addresses can be found on:
http://www.swiftdsl.com.au/ADSL-web-hosting.htm
However in deciding on how many additional IP addresses you need you need to understand that not all addresses in any block are usable by you.
The following gives you the actual number of addresses allocatable by you from each block:
/32 1 address, special case known as a Host address, 1 useable
/31 2 addresses, 0 useable
/30 4 addresses, 2 useable
/29 8 addresses, 6 useable
/28 16 addresses, 14 useable
/27 33 addresses, 30 useable
/26 64 addresses, 62 useable
/25 128 addresses, 126 useable
/24 256 addresses, 254 useable

Are you able to purchase 1 extra ip address ?
looking at this to enable static NAT so my cisco vpn connection will work
|
|

|

The minimum block of additional IP addresses you can 'purchase' is four;
Which gives you two usable addresses.

1) What information they require, and in which format
2) Limitations on reverse DNS on the Swiftel end of things.
I'm about to migrate my domains, and want to have the reverse DNS ready to go before I do so.
Best regards,

You can send your request to adslsupport@swiftel.com.au .
There are no limitations - we will provide you will reverse delegation on the entire block you have purchased.
The best format for us is to send the PTR records you want so we can just cut an paste them into the zone file, eg:
IP address IN PTR hostname
which looks like:
243 IN PTR p-nya.swiftel.com.au.
A less preferred format is if you just list the IP address and the hostname you want.

How come only some of the other ips are usable.
What does that mean

What does that mean Generally you can't use the 'all 1's' and 'all 0's' part of the subnet block as host addresses, which preculdes the first and last address in that block.
Here is a whitepaper from 3com that explains it:
http://www.3com.com/other/pdfs/infra..._US/501302.pdf
and another one from Cisco:

Question, can you route 4 /32's down an adsl and just alias the 4 ips on the firewall, that way we don't waste IP's
My guess too much admin to be done

Yes, you can treat a /30 as four /32's.
We still route the subnet the same way to you, but your modem/router has to treat the subnet as four host addresses.

Do you need a special router for the additional IP's gain a connection.
Or can you just assign those machines the static IP's and it works?
We have several servers which need real world IP's to point traffic at.

If I understand your question then no, you do not need anything special, an NB1300 Modem/router or something similar will be fine.

Do Blocks of IP's of 8 or more require network documentation to justify their use, like iinet and westnet demand?
|
|
|

"Do Blocks of IP's of 8 or more require network documentation to justify their use,"
Yes;
It is an APNIC requirement.

Hi!
I was wondering, I am a new subscriber to Swiftel ADSL and one of the things that we liked was the static IP option.
How do I find out what our IP address is??
your held would be great!
|
|
|
|
|
|
|
|
|
Go to the CMD Prompt and type in ipconfig.
|
|
|
|
|
|
|
|
|
I knew it was something really simple.
:-)

I would like to know once you have more then one ip assigned to your connection how do you use/ switch ip's for say web hosting?
|
|
|
|
|
|
|
|
|
That page is now 404 and there is no metion of additional IPs on the pricing page.
Plus I was wondering how it worked?
Like is there a PPP IP and then the LAN gets other IPs, or is it like some sort of bridging involved?

Mmmm... Telstra Internet Direct dish them out without much questioning...
Also, methinks Swiftel marketing bods should be ashamed of the way they marketed the block-IP stuff on their website.
http://swiftdsl.com.au/corporate/ADS...hosting.htm#IP
Yes, anyone who deals with this stuff knows that a /29 has 8-2=6 usable IPs, and a /30 has 4-2=2, but that page is so vague as to whether its talking usable or actual, its bordering on deceitful.
Even the addtional-IP order form doesn't even make clear the difference.
Shame Swiftel Shame!!
This is the only complaint I have about swiftel so-far.
Otherwise, they're TOPS!!

Hery there was a question raised before why the addresses have to be broken down into the network and broadcast addresses.
Why can I have 4 ip (if I select the additional 4) available to me
for instanance why can't I have all 4 ip's on my linux firewall machine (using usb bridging)?

[/b] If you're asking why you can't use all 4 IPs, its cause the CIDR extension (??) of the IP protocol and the IP protocol itself, says you can't.
IP doesn't care what hardware you're using.

I realise what the CIDR mentions, but why can they simply route 4 /32's down the line ?
|
|
|
|
|
|
|
|
|
AFAIK, its because the IP protocol dictates that you can't, two addresses not being available.
Like I said, IP doesn't care what Layer 1 systems you're using, so your having hardware that can't broadcast makes no difference.

Understand, but don't route it as a network, route it as 4 /32 !

Yes, I see what you're saying now.
Like you probably said before (or are thinking), maybe just to avoid the overhead.
Dunno.

I have 3 more questions:
Is it possible for the usage page to meter what each IP has downloaded separately?
Is the $150 paid upfront?
If it is can there be a pro-rata refund if ADSL is cancelled within the first year?
I would like custom reverse DNS on all them, will it be treated as "one" or "six"?
(ie Will it be $20/year or $120/year?)

Possible, but I seriously doubt whether they'll do it.
Thats your job if you have multiple.

Yes, of course.

There are no refunds for up front payments either in full or pro rata.

Another thought:
what if you own (administer/etc) your own block of addresses ?
Is swftdsl willing ro route them for a user ?
-G
|
|
|
|
|
|
|
|
|
Yep they have, do and will, The minimum advertisement they would make is a /24 though.
|
|
|
|
|
|
|
|
|
Then I guess its a good thing that i have a /24 network.
I will wait for the initial line activation to be done (again...properly this time) before I even think about this
I guess the next question is ...
Its my range ... do I get charged by swiftdsl for it ?

Hi,
Regarding the equipment required and setup of the computers, do you just turn NAT off on the router/modem and set the IP addresses on each of the computers you have purchased static IPs for?
Cheers,
Adam.

Quote: : The minimum block of additional IP addresses you can 'purchase' is four;
Which gives you two usable addresses.
Hi all,
Could someone please provide me with some information re additional IPs?
I currently have a static IP and am considering purchasing an additional block of 4 IPs (2 usable) to host an additional SSL website.
I understand that my ADSL Modem/router will need to have NAT disabled and I would add the two usable IP's on my internal server(s).
My main queries are:
1.
Will my current IP still be usable, effectively giving me 3 usable IPs?
2.
Will I need to enable RIP on the router, and if so, which version?
I have a Netgear DG834 which supports RIP-1, RIP-2B and RIP-2M and would it need to be enabled in both directions?
3.
What goes on the LAN interface of the router?
The broadcast address from the IP block?
Please excuse my ignorance
|
|
|
|
|
|
|
|
|
Hmm sorry can't help on most of that, yet I think you only get 2 usable ip's.
but I have to say, I get an email warning me of a new post on this thread!
After like a year!
Haha that's pretty funny.

I have a block of 8 with 6 usable - and they are worth their weight in gold.
Multiple routers, multiple networks.
Can trial different servers, different os's, different security systems and routing and filtering techniques all without affecting my main server and office network.
I use an alcatel speedtouch pro to do the main routing - I just disabled firewall and nat, setup the ip as suggested and it worked like a charm.
I have all my secondary servers / routers plugged into the speedtouch pro and a little 8 port hub connected to it.
The availability of multiple IPs is the key reason I am a swiftel client.
Shame the next level up costs $500.

Thanks Xenek.
So does this mean that my current IP address becomes unusable, requiring me to change ALL my DNS records?
What happens with the two unusable IPs from the block?
Did you have to specify them anywhere?
Regards.
Nathan.

Is there currently a delay in obtaining a block of 8 ip's ??
Faxed an application in on the 4th of this month and havent heard anything back as yet.
Got a block organised for work last November and it was only a few days..

John

3 weeks since I faxed the application in and still nothing.
Is the staff member who allocates IP blocks on holidays ??
Would appreciated it a peoplenet person would get onto this..
