[quoteFor Activating RDNS you have to create a Reverse zone but delegation is necessary thus you have to buy a complete block of IP address (i.e from ARIN) to setup RDNS

Reverse DNS is shown the owner of the IPs[/quote]

That is not entirely true. We run rdns and do NOT have our block directly from ARIN. You need one of three things:

1) Your block SWIP'd to you including your DNS server info. You then need to have the entries on your DNS servers.

2) Your upstream provider to provide rdns for you.

3) A provider who uses rwhois delegation with your dns servers listed in their database in which case you can use your own DNS for this.

I'm not agree with you because SWIP templates should be submitted by your ISP (Network Access provider) who has received IP block directly from i.e. ARIN
(for those who don't know what is SWIP: SWIP stands for Shared Who is Project and is a Process used by ISPs to submit reassignment information to ensure effective, efficient maintenance of records. )

It means you can not oblige them it depends on your ISP to accept or deny which they usually deny rDNS requests unless you are the owner of the block of IP

I'm not talking about exceptional cases which ISPs accept your requests for providing rDNS to you but in most cases (usually) they don't. (if you would like I'll show you why they legally can argue to you why they don't accept )

What I wrote in my last post was about conditions not the process; if you would like I can write a complete step by step instruction on this issue too.

for you kwimberl, as you can see the result of what I wrote is the same as what you wrote in most cases, I don't want to argue anything just want to help.

ITF,

what is the minimum block of IP that we could ask from upstream provider to submit SWIP and reassigning to us, then we have IP whois data and rDNS service ?

officially /20 (but some ISPs break the rules)

Statistics show that it does not affect on your hosting business. (sales)

I never said that the individual requests the SWIP. I simply listed the ways to do rdns and that your solution was not 100% complete nor accurate. You stated that rdns shows the owner of the IPs which is not always true.

None the less, the way to go about getting rdns done is to ask yuor upstream for help. More than likely, they will just do it for you.

As for us, we have 9 /24's (class C's). I have them SWIP'd and we control our own rdns. However, our clients contact us for rdns and we do it for them. We don't SWIP to them unless they have at least a /25.

I don't think you have the correct understanding here. Perhaps you don't really understand that IPs can be allotted to more than one party. In other words, company A can own the IPs and SWIP them to company B (their client). They can even then be SWIP'd to company C.

Here's a good example:

http://ws.arin.net/cgi-bin/whois.pl?queryinput=64.57.209

That is one of our blocks. Because of our setup, we have each /24 (class C) SWIP'd individually.

There is no ARIN rule that says that less than a /20 cannot be SWIP'd. That is far from the truth. In fact, ARIN recommends that ISP's SWIP or provide rwhois data for their clients. I'd love to see you try and get more IPs from ARIN without having SWIP'd a good percentage of your current ones.

ARIN will not assign less than a /20 to an ISP directly as a normal matter of course. This may be what you are thinking. There are, however, exceptions to that too.

Everyone knows that ARIN is not a lawmaker, they exist just to handle and manage the assignments when I wrote breaking the rules I meant “common rules” or usual , may be you prefer a legal word “precedence”

Also if you read my post about rDNS you can see that [b:28f66847e4]I didn’t wrote:[/b:28f66847e4] &it is impossible&, if your ISP accepts then there isn’t any problem.

I wrote this in my post: &For Activating RDNS you have to create a Reverse zone but delegation is necessary thus you have to buy a complete block of IP address (i.e from ARIN) to setup RDNS&

I didn't wrote that you have to buy from ARIN I just wrote (i.e. from ARIN) means in example from ARIN, that was an example I think everybody knows that you can buy IPs from ISPs, and my post just shows that you have to own a block of IP.

however rDNS doesn’t show the IP user always but it was designed for this purpose
You are right the Block owner can reassign it to another user depends on their policy but ISPs [b:28f66847e4]must[/b:28f66847e4] submit SWIP and offer rDNS for /20 block (and greater blocks); [b:28f66847e4]for lesser blocks it depends on their policies.[/b:28f66847e4]

Also what I wrote in my previous posts about this issue were some Hints not a complete instruction which is not necessary because upstream providers should do most of steps.

Kwimberl we are talking the same way, but unfortunately you don’t focus on definition of the words. F.Y.I I was working for the ARIN , also now we rule our rDNS and IP blocks too.
