Re: maximum ipv4 bgp prefix length of /24 ?

I think the fact that RIR's allocate very large IPv6 address space to their members may well be what is driving this. Historically, network operators do enjoy de-aggregating address space. One can get significantly more /48's out of a /32 (or shorter) than they would /24's out of any IPv4 allocation they acquired. One way to control this escalation is to shorten the maximum prefix length that all operators are willing to accept into the DFZ. The other way would be to get RIR's to lengthen the minimum allocation they can make to their members. Neither of these solutions is likely to be popular, but nor is having to pay large sums of money for more FIB. Mark.

cogent spamming directly from ARIN records?
by Mel Beckman 04 Oct '23

04 Oct '23

This morning I received an email from someone at Cogent asking about an ASN I administer. They didn’t give any details, but I assumed it might be related to some kind of network transport issue. I replied cordially, asking them what they needed. The person then replied with a blatant spam, advertising Cogent IP services, in violation of the U.S. CAN-SPAM Act’s prohibition against deceptive UCE. I believe they got the contact information from ARIN, because the ARIN technical POC is the only place where my name and the ASN are connected. I believe this is a violation of Cogent’s contract with ARIN. Does anybody know how I can effectively report this to ARIN? If we can’t even police infrastructure providers for spamming, LIOAWKI. -mel beckman

ARIN Election

Does anyone know how many people will be elected from each category? I don't regularly keep up with everyone's business. So, are any of candidates overachievers or, well, underachievers? Nich Warren

Re: maximum ipv4 bgp prefix length of /24 ?

Among the issues: Suppose the FIB has all the /24 components to make a /20, so it programs a /20. Then one of the /24's changes nexthop. It now has to undo all that compression by reinstalling some of the routes and figuring out the minimum set of /21, /22, /23, /24 to make it happen. Then to avoid a transient, it needs to make before break. Quite a bit of FIB programming needs to happen just to modify a single /24. Then the next /24 in the set also modifies its nexthop. and so on for 100000 routes. All because a peer link flapped. Affecting convergence. Then you need to buy a line card that can hold all the individual routes, because you can't always compress, because not all the routes in your compressed set have the same nexthop during a transient. Finally, it's all nicely compressed. Now what? You have lots of empty slots in your FIB. I'm sure lots of nerds can come up with transient reduction algorithms, but I'd rather not. Kind Regards, Jakob --------------------------------------------------------------- Date: Sat, 30 Sep 2023 20:04:29 -0700 From: Owen DeLong <owen(a)delong.com> Not sure why you think FIB compression is a risk or will be a mess. It?s a pretty straightforward task. Owen

maximum ipv4 bgp prefix length of /24 ?
by VOLKAN SALİH 02 Oct '23

02 Oct '23

hello, I believe, ISPs should also allow ipv4 prefixes with length between /25-/27 instead of limiting maximum length to /24.. I also believe that RIRs and LIRs should allocate /27s which has 32 IPv4 address. considering IPv4 world is now mostly NAT'ed, 32 IPv4s are sufficient for most of the small and medium sized organizations and also home office workers like youtubers, and professional gamers and webmasters! It is because BGP research and experiment networks can not get /24 due to high IPv4 prices, but they have to get an IPv4 prefix to learn BGP in IPv4 world. What do you think about this? What could be done here? Is it unacceptable; considering most big networks that do full-table-routing also use multi-core routers with lots of RAM? those would probably handle /27s and while small networks mostly use default routing, it should be reasonable to allow /25-/27? Thanks for reading, regards..
