Hello Angelo,
You are correct, an ASN (Autonomous System Number) is just a number, although often you will see it with “AS” before it, e.g. AS12345
There are generally speaking two ways folks announce their 44-net prefixes…
1) If you have your own ASN and suitable equipment in a suitable location etc, then you can setup a BGP session on your own equipment and announce your prefix to your ISP/NSP. In which case the originating ASN would be yours and the NSP details would be the organisation you announce to (there may be more than one NSP if you are multi-homing).
2) You don’t have your own ASN and your ISP/NSP will be announcing your prefix for you. In which case the originating ASN will belong to your ISP/NSP.
In your case, it sounds very much like 2) so on the form I sent you, you need to put your NSP’s ASN as the originating ASN, either in the format 12345 or AS12345 I don’t mind which! So you just need to ask your ISP/NSP what their ASN is.
Your ISP is no doubt connected to multiple providers but I don’t need to know about them, unless they specifically request that they are mentioned in the LOA - which occasionally happens.
I thought I would reply on the mailing list in case this helps others.

Hi Guys,
I am trying to locate two pieces of information to be able to complete my BGP request.
This seems to be more of a challenge then I though it would be. Is there a reference page or
wiki that I can provide to my ISP to be able to locate this information.
We have been dealing with these two questions for over 2 weeks. I am not sure if the ISP or the
NSP know exactly what we are looking.
From what I understand the ASN is just a number. No letters involved in this number. Is this true???
Any help in providing information to the NSP would help.
Break Down - I will be connecting to ISP via VPN connection.
The ISP connects to his feed in Houston via I ATT fiber connect to his NSP in Houston. The ISP sell service to clients in his area. He has a /6 himself.Please don't laugh. I am trying to lay this out the best I can. Any help would be appreciated.
