Fwd: Re: Re: What is the most standard subnet length on internet
by 정치영 19 Dec '08

"You have to change your server's IP address if you want move your server to other place" -> It is very natural case, but some customer could think of it will be okey to move if they have C class. but I have different idea. because the border router of that center is annoucing more greater IP block, and if customer move to other center with C class, then I have to newly announce that C class at the border router of other center. and then it is the time my hierachy structure is broken. To prevent this situation, I'm trying to find some standard material every person would understand and accept. ============================================= Chi-Young Joung SAMSUNG NETWORKS Inc.

It seems so simple. Currently annoucement of /24 seems to be okey, most upstream providers accept this. However I wonder if there is any ground rule based on any standard or official recommandation. If there is some standardized rule about prefix length to be annouced, I will make my bgp & IP allocation policy of each data center of my company, and I will be able to more fairly and squarely speak to my customer like this "You have to change your server's IP address if you want move your server to other place" chiyoung ============================================= Chi-Young Joung SAMSUNG NETWORKS Inc.

Do you mean IP allocation as in subnet allocation, swipping in apnic or through a rwhois server etc? Or do you mean "what is the minimum subnet size I can announce on the internet and have other providers not drop it on the floor"? srs On Fri, Dec 19, 2008 at 8:10 AM, 정치영 <lionair(a)samsung.com> wrote: > Hi everyone, > > I'm going to rebuild IP allocation policy of my company and I am looking for some standard reference for my policy. > I have already studied some standard like RFC1518, RIPE181, RFC2050 and I got it is very important to maintain hierachy structure. > However, what I am really wondering is what is the most standard subnet length that always can be guaranteed through Internet. less than /24 bit ? > I could not find any documents about that, which subnet length is most proper value and pursue internet standard policy ? >

What is the most standard subnet length on internet
by 정치영 19 Dec '08

19 Dec '08

Hi everyone, I'm going to rebuild IP allocation policy of my company and I am looking for some standard reference for my policy. I have already studied some standard like RFC1518, RIPE181, RFC2050 and I got it is very important to maintain hierachy structure. However, what I am really wondering is what is the most standard subnet length that always can be guaranteed through Internet. less than /24 bit ? I could not find any documents about that, which subnet length is most proper value and pursue internet standard policy ? Could anyone give me some information guides ? Best wishes, Chiyoung ============================================= Chi-Young Joung SAMSUNG NETWORKS Inc.

Arbor vs Narus comparison?
by andy lam 19 Dec '08

19 Dec '08

Recently I've been searching for something that is comparable to Arbor to see what else is out there. Someone suggested Narus. Anyone out there have an opinion regarding the 2 applications and their differences? Or another application that is worth noting? I am currently using Arbor Peakflow for Netflow analysis against my peering/transit traffic and their Security suite to identify DoS, etc at the edge. Feel free to contact off-list. Thanks

Global Crossing SOC
by Fouant, Stefan 17 Dec '08

17 Dec '08

Folks, Any Global Crossing SOC folks here? We've had a simple DoS attack targeting one of our nodes connected to Global Crossing but have literally spent 3 hours on the phone with Global Crossing support attempting to get someone with a clue as to how to implement a simple ACL on their edge router to deal with this. If there's anyone here who can assist, please contact me off list. Regards, Stefan Fouant: NeuStar, Inc.
