IP Allocations
by Mark Cobb 13 Aug '99

13 Aug '99

I have a question about how much IP space to allocate for downstream customers. I know that when we want to obtain IP space that we have to go to ARIN with the proper justification forms to show that we have effeciently utilized our assigned IP CIDR's and also to verify that they have been SWIP'd, etc... We also offer transport, so I came up with a basic "rule of thumb" to use as a guideline. Up until recently, this has worked fine. Now I am uncertain of what I should do with a customer that is requesting a /23 CIDR, yet they only have 256K bandwidth. Part of me says give it to them and let thier customers deal with the service that they will receive, but then I feel obligated to not support bad ISP service. I guess that I am looking for an industry guideline as opposed to the one that I am trying to use or if I should even care. I use the following: 256K = /26, 512K = /25, full T1 = /24, etc.. Let me know what everyone thinks, is this fair or not, and should I care??

Re: POWER: Chicago, IL power problems

Commonwealth Edison now estimates it will be 18-22 hours before the power is restored. The blackout area has already expanded once, and CE may have to shutdown more areas to complete repairs. The affected area is bound by Adams Street on the north, Roosevelt Road on the South, Dearborn Street on the West and Michicgan Avenue on the east. ISP/Telco infrastructure affected: Currently ISPs are reporting that Ameritech ISDN service center can't test any ISDN lines. Two major CLEC/IXC facilities are in the blackout area, and are on backup power. Several smaller CLEC/ISPs also report they are on backup power. If you get out your Mapquest, the Chicago NAP is outside the current blackout area, and is currently unaffected. It has its own backup generator just in case (see, some good things do come from Y2K :-) Since the 18-22 hour estimate exceeds the normal 4-8 battery life telco's use on equipment in non-CO office buildings, there may be some additional outages as muxes and equipment in out-of-the-way places run out of power. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

DNS Flood
by Jamie D. 12 Aug '99

12 Aug '99

Are there any other ISP's who are experiencing DNS floods, specifically I am looking for traffic destined for (or coming from) the following IPs >>> 199.108.32.203 >>> 216.15.178.201 >>> 129.180.11.17 >>> 216.41.23.68 >>> 208.235.124.20 >>> 203.251.77.1 It appears someone is running a script that is using these nameservers, as well as the name servers of other educational facilities, to do a lookup on mulitple servers in the amplitude of 3-4 a second. This activity has been happening for the past 3 weeks, we have null routed this traffic on our backbone, but it still shows up in Cache flow. This traffic actually saturated our customer's pipe as well as increased the load on our backbone router. If anyone has seen anything at all like that, (specifically people from UU.net or AT&T Worldnet) please lets band together and find the person doing this.

Jamie, Yep. I'm seeing the same list of suspects hitting various destinations. I have multiple backbone connections and the traffic from these nodes is comming from GTEI, IBN, and over MAE-LA. I can't tell if the source addresses are spoofed. Walt

POWER: Chicago, IL power problems
by Sean Donelan 12 Aug '99

12 Aug '99

Commonwealth Edison has lost several large transformers feeding the the "West Loop" in Chicago. Commonwealth Edison reports the outage is in the Jefferson substation at 828 S. Jefferson St. starting around 10am CDT. There are some major ISP/Telco facilties near that area. At the moment, the ones I was able to reach report they are up on backup power. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

was in-addr.arpa question, now BBN

In message <01JEMIE2WJS691XASM(a)ACES.COM>, Ehud Gavron writes: > BBN still thinks they invented tcp/ip. And we have a pretty good claim. If you go back and look at the history of networking in the 1970s, BBN was a very active participant -- probably more active than any other corporation. And BBNers figure prominently on early drafts of many of the major protocols we know today, including TELNET, FTP, email, the New ARPAnet routing protocol (the protocol that OSPF and IS-IS are based on) and EGP (predecessor to BGP). We've occasionally tooted the horn a bit too strongly (there's a famous report c. 1980 that some Internet pioneers periodically bring up :-)) but we're certainly entitled to toot it. Thanks! Craig Partridge Chief Scientist, BBN Technologies (part of GTE) PS: BBN Technologies does research. What was BBN Planet is now GTE Internetworking. So sending me day-to-day operational questions is generally a waste of time. (I'm on this list to track issues in future operations...)

Software Started MCI Outage
by Henry R. Linneweh 11 Aug '99

http://www.zdnet.com/intweek/stories/news/0,4164,2312942,00.html According to MCI WorldCom spokeswoman Linda Laughlin, the carrier was upgrading a switch somewhere on the frame relay network when the device began to "experience congestion" and the initial outage began. Laughlin was unable to say where the faulty upgrade occurred or what the upgrade was for. Henry
