IP utillization software
by Tim Finkenstadt 18 Aug '99

18 Aug '99

Greetings. I am looking for IP address utilization software for the following purpose: I work for a very large company with lots of facilities and offices. Our group needs to reclaim the space that was previously allocated before the days of VLSM. For example: facility allocated 172.28.32/19 . I want to be able to find out how much that facility is utilizing. thanks, tim

snmpstat monitor ver. 1.2.e - see http://noc.bn.ru/~alex/MON
by Alex P. Rudnev 18 Aug '99

18 Aug '99

I completed, as promised, the work of collecting distribution pack for the snmpstat monitor (version 1.2.e, where 'e' means _english menu available_). The system was tested for the FreeBSD and Solarys 2.6, but I believe it can work fine on any Unix where CMU SNMP library can be translated. This pack include: - the russion and english dicumentation; - the installation pack (tested for the fixed /p/stat and user: monitor group: monitor configs but theoretically allowing to use any location and user), including snmpstatd daemon, WWW interface to the monitoring system, LINKS data base and WWW interface for it, and (in addition) modems_poll monitor (withouth any WARRANTIES and docs). This (1.2) is SHAREWARE software - we ask you to contact us in case this appear to be usefull for your market or provision work, if you are the commercial company. I can't promise the next (with the object priorities, snmp polling of the modems, service monitoring etc) version should be just as free as this one, but it should not bee 100% commercial anyway.

At about 9:30 UTC h.root-servers.net was returning NXDOMAIN for most though not all .com domains. For example, amazon.com and netsol.com were broken. msrl.com worked, but all of its nameservers are in .net; ibm.com worked, but all of its nameservers are within ibm.com and are covered by glue records. The pattern seemed to be that any domain with all of its nameservers in .com but outside of its own zone would fail to resolve from h.root-servers.net. I only tried about a dozen domains so the actual pattern may have been different. I sent a mail this morning to hostmaster(a)internic.net (with no response of course, but that's the SOA contact for .) and cc'd to nanog (but I had neglected to subscribe to nanog-post). It's interesting that there was no mention of this outage, which caused hard mail bounces and other problems. -- Shields.

Shared network services and transit providers
by Sean Donelan 15 Aug '99

15 Aug '99

Shared registries and backup, note: this is not intended to be NSI bashing. Although NSI receives free transit from a number of backbone's, it appears NSI is only announcing its own registry via the free transit it receives. The shared registry whois.crsnic.net appeared to be single-homed through Sprint today. This came up, because there was a network problem reaching whois.crsnic.net, but it didn't affect NSI's own service. I also looked at several of the other well-known registries. From my network vantage point (BGP only shows the 'best' transit): ARIN seems to have at least two ISP connections, RIPE at least three connections. APNIC appears single-homed through Telstra, I guess shouldn't be surprising since its in Australia. Are these shared services important enough for network operators to try to coordinate multiple connections for them? Or with competition coming, let them each do whatever they want? -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

The Cidr Report
by Tony Bates 13 Aug '99

13 Aug '99

This is an auto-generated mail on Fri Aug 13 12:00:00 PDT 1999 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Reminder: Ameritech EP renumbering
by Mark A. Cnota 13 Aug '99

13 Aug '99

This is a reminder to everyone about the renumbering activity this weekend. Customers received the below note several weeks ago. Please e-mail if there are any questions. -Mark --- To customers of the Ameritech ATM exchange point in Chicago: As previously announced, Ameritech will be changing the address space used for customers at the exchange point. The current space was formerly managed by ISI as part of the Routing Arbiter project but is now administered by JAM. The new space has been allocated directly to Ameritech, specifically for the Chicago exchange point, and will be managed by Merit Networks. This change will involve a one-time renumbering effort for all customers. In order to allow for as much coordination and preparation among customers as necessary, we are giving everyone an extended forward notice of this activity. The scheduled date for the renumbering is Sunday, 15 August 1999. In the next few weeks, further information including new address assignments will be made available on our web site, http://nap.aads.net. Questions should be directed to nap-info(a)nap.aads.net.
