Re: [44net] ASN # and Network Service Provider (NSP)

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. 73, Chris - G1FEF
