[admin] Using the NANOG list as a paging mechanism
by Martin Hannigan 09 Jan '08

09 Jan '08

Hi Folks, We'd like to politely note that paging each other on the list without content or context is generally off-topic. These messages are perceived by many as fragments that are not useful to the wider community. If you could provide some level of detail as to why you are using the list to reach someone, it would be much appreciated. There are many benefits to this approach including more eyes on the issue (and the message) as well as a faster MTTR. If the issue is not involving the public Internet, then it's probably safe to conclude that a private approach may be better. Best Regards, Martin Hannigan NANOG Mailing List Committee

Re: Assigning IPv6 /48's to CPE's?

>* /32 for ISPs unless they can justify more >* /48 for subscribers unless they can justify more >* /64 when you know for certain that one and only one subnet will ever be required >* /128 when you know for certain you're dealing with a single device >* Sparse allocation so whichever size you choose you can usually increase it by simply changing the prefix length. So if /64 is "subnet" rather than "node" then the practice of placing one and only one node per subnet is pretty wasteful. And giving residential users a /48 will leave them with 80 bits for addressing. Even if the household was using 1,000,000,000,000,000 IP addresses in their home, this would mean that they are still not using 99.9999999% of the IP addresses they have been allocated. I know the reason for this is becasue they are allocated IP's based on number of possible subnets, rather than total number of available IP's, so it would be more fair to say they are allocated 65,536 subnets. So Acme DSL has been given a /32 from ARIN. Bob their administrator promptly decides it is a good idea to just give each customer a /48 becasue who knows /what/ their needs may be. This gives Acme Bob enough IP addresses for 2^(48-32) or 65,536 customers assuming bob uses none of these IP addresses for his own equipment and has a single homed network. If Bob has a multihomed network, he can't just give one /48 to a customer in NY and the next one to a customer in CA unless he wants to fill up Internet routing tables with /48's, so he will have to assign large aggregate blocks to each region. Accommodating for this, Bob is unlikely to plan for more than 30% utilization in any one region, with most being less and some aggregate blocks withheld entirely for growth. So lets say Acme DSL's IPv6 deployment places them in the ballpark of 10% utilization (not bad considering end users are wasting 99.99999999999999999999%), this gives them enough blocks for only 6,500 customers. Take someone like Comcast with ~12 million subscribers. It would take an IPv6 /24 to get 16.7 million /48's (2^24). With a net efficiency of 10% they are going to need to be allocated 120 million /48's. It would take a /21 to give them 2^(48-21) = ~134 million /48's. So in short, a /48 to subscribers seems like complete overkill, and a /32 to ISP's seems completely inadequate (80 vs 16 bits). I thought one of the goals of IPv6 was to assign ISP's huge blocks with low utilization so they don't have push a bunch of individual prefixes out to the worlds routing tables? It seems to me while being extra super sure we meet goal 1 of making sure NAT is gone for ever (and ever) we fail goal 2 of not allocating a bunch of prefixes to ISP's that are too small.

SMTP addresses in <>
by Seth Mattinen 07 Jan '08

07 Jan '08

I'm having a bit of an argument with a customer over the command syntax in RFC 2821 that shows command arguments for MAIL/RCPT commands in brackets, i.e.: Path = "<" [ A-d-l ":" ] Mailbox ">" Mailbox = Local-part "@" Domain Our mail servers reject connections that don't follow the RFC. Am I wrong to do this? This guy certainly thinks so, even after I've cited the RFC and appropriate section, his arguments is "even hotmail does not keep up the standards" and if we ignore them as well. Hotmail at least follows this rule... am I wrong to require the brackets? ~Seth

Looking for a contact @ XO
by Drew Weaver 07 Jan '08

07 Jan '08

Howdy, I apologize for using the list as a 'paging mechanism' but I have exhausted all possible avenues towards reaching a solution to a simple issue with XO including their help desk, their abuse desk, any old contacts I may have had, their local sales office, their old NNTP contact address, their BGP address, and so-on. (just to make it clear I have exhausted all of the possible avenues before attempting to use this one) We're running up against a very serious security/abuse issue and if anyone knows of, or is the proper contact (not the address published in the ARIN records because that apparently is not the appropriate address as they appear to be clueless) I would appreciate any help you can offer. I already realize that some folks believe that using the list as a 'paging mechanism' isn't favorable and there is currently a discussion going on in another thread about that so there really doesn't need to be another one started here regarding that on-list, or off. Thanks. -Drew

Out of curiosity, what in form would a request for a /48 need to be? A checkbox on the application form, or some sort of written justification? Remember that with an initial RIR allocation of a /32, you've got 65K /48s ... so they're pretty cheap to give away. --------------------------------------------------------------- I have about 100K DSL customers at this time and most all are households. 65K wouldn't cover that. At this point, I doubt that I'd require much more than just asking and making sure the person is understanding what they're asking for. Mostly, that'd be the leased line customers. scott

DreamHost Contact?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've attempted to contact DreamHost NOC or Abuse departments via the numbers in whois but just get voice mail and no call back. I've got a user sending a lot of UDP traffic to 208.113.189.13 port 22. This traffic is very likely undesirable and I'd be willing to pull the plug immediately if I can get confirmation from DreamHost.
