Bot reporting - best procedure?
by Simon Waters 16 Nov '10

16 Nov '10

Sure it is something I should know, but I keep hitting dead ends. What is current state on botnet reporting procedures? A minor irritation currently, but clearly well resource botnet is pestering one of our services, only a couple of thousand IP addresses in use, but I'd like to mop up as much of it as possible whilst it is only an irritation, since presumably between irritation and being off the Internet is only one command. Lots of Botnet related resources seem to have vanished from the net, or be in poor repair. RIPE provide an API for Abuse address lookup, so a potential solution exists for automaton. But I figure someone else will have written some scripts or interfaces to save me messing it up, and landing 100's of abuse desks with useless information.

They provide a back-up DNS service but under the assumption that they are backing up your server. I should not be that difficult to setup delegation with your primary DNS provider.

Questions about radio resource allocation in 3G data network
by ¹â¹â 15 Nov '10

15 Nov '10

Hi everyone, I have some specific question about radio resource allocation in 3G data network. In the UMTS 3G data network, the smartphone has to acquire radio resource from RNC before it can talk to any server on the Internet. Allocating radio resource usually takes a few seconds (2+ seconds) to complete and thus causes delays to the smartphone applications. This process will involve RRC connection setup and radio bearer reconfiguration. From my observation, the delay caused by the radio resource allocation varies a lot over time and seems it is not only caused by the radio access network. So I was wondering what network devices are involved in the radio resource allocation besides the phone, base-station and RNC? And what are the factors that can potentially affect the observed delay? Thanks a lot! -Gary

Re: Register.com DNS outages
by esanborn＠tsd-inc.com 14 Nov '10

Yes, however register.com does not allow their customers to list both their DNS servers and a customer's DNS server. End result is when the outage on their servers occurs you need to modify the config on their website so that it points back to your private DNS servers. Propagation delays are a pain.... ----- Original Message ----- From: Florian Weimer <fw(a)deneb.enyo.de> To: Brandon Kim <brandon.kim(a)brandontek.com> Cc: nanog group <nanog(a)nanog.org> Sent: Sun Nov 14 13:48:55 2010 Subject: Re: Register.com DNS outages * Brandon Kim: > Times like this, makes you curious what kind of infrastructure > register.com has? How does one protect against DDOS? You can outsource your DNS, but you better retain a server locally on your network, so that you suffer less from that particular shared toothbrush.

Recent operational experience choosing between PBB-TE, MEF9+14, VPLS or T-MPLS ?
by Francois Menard 14 Nov '10

14 Nov '10

I'm embarking on a new project which involves a large scale MAN network where ultimately, the objective is to carry QinQ, while at the same time delivering services over IPv6. The objective is to support jumbo frames on all interfaces, at least to carry QinQ standard-size ethernet frames, but ideally as large as possible There seem to be 4 approaches to do this. a) The IEEE PBB-TE approach - but little implementations. b) The MEF9+14 approach, mature, but manual provisioning c) The VPLS approach, concerns with too much manual provisioning. d) The T-MPLS approach, concerns with maturity The objective is to support the functionality not only in the CORE, but also on cost effective multi-tenant & redundant customer CPEs. I have not seen a, or b or d supported in a low-cost customer CPE. I am currently favouring c, for reasons of maturity and wide implementation, but may be missing on recent progresses in the b) land. Any thoughts ? Any published IETF material on the topic ? F.

105/8 allocated to AfriNIC
by Leo Vegoda 13 Nov '10

13 Nov '10

Hi, The IANA IPv4 registry has been updated to reflect the allocation of a /8 IPv4 block to AfriNIC in November 2010: 105/8. You can find the IANA IPv4 registry at: http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xhtml http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt The complete list of IPv4 /8s allocated so far this year is: 1/8 14/8 27/8 31/8 36/8 42/8 49/8 50/8 101/8 105/8 107/8 176/8 177/8 181/8 223/8 Please update your filters as appropriate. The IANA free pool contains 11 unallocated unicast IPv4 /8s. Regards, Leo Vegoda Number Resources Manager, IANA ICANN
