Hi, Could someone from Savvis contact me off-list please. We have been stuck behind a route-loop since last night's maintenance: traceroute 208.91.191.1 traceroute to 208.91.191.1 (208.91.191.1), 64 hops max, 40 byte packets 1 FE0-0-12.nav1.nyc.access.net (166.84.1.28) 0.443 ms 0.568 ms 0.456 ms 2 port-channel1-128.l3core.nyc.access.net (166.84.66.1) 1.359 ms 1.000 ms 0.977 ms 3 gi0-7.na21.b001105-3.jfk02.atlas.cogentco.com (38.102.195.129) 1.499 ms 1.788 ms 1.312 ms 4 vl3608.mpd01.jfk02.atlas.cogentco.com (38.20.32.61) 1.861 ms 1.695 ms 3.223 ms 5 vl3493.mpd03.jfk02.atlas.cogentco.com (154.54.5.226) 2.714 ms te2-3.mpd03.jfk02.atlas.cogentco.com (154.54.3.1) 2.482 ms vl3493.mpd03.jfk02.atlas.cogentco.com (154.54.5.226) 2.634 ms 6 te8-3.mpd01.dca01.atlas.cogentco.com (154.54.5.98) 12.221 ms 8.209 ms 9.022 ms 7 vl3498.mpd01.dca02.atlas.cogentco.com (154.54.7.6) 10.168 ms vl3492.mpd01.dca02.atlas.cogentco.com (66.28.4.86) 8.746 ms 11.408 ms 8 vl3496.mpd01.iad01.atlas.cogentco.com (154.54.5.46) 17.866 ms vl3494.mpd01.iad01.atlas.cogentco.com (154.54.5.42) 11.052 ms vl3497.mpd01.iad01.atlas.cogentco.com (154.54.5.66) 8.642 ms 9 ber1-ge-7-43.virginiaequinix.savvis.net (208.173.10.181) 8.604 ms 8.954 ms ber1-ge-7-39.virginiaequinix.savvis.net (208.173.52.105) 8.373 ms 10 * cr1-tengig0-7-2-0.washington.savvis.net (204.70.197.242) 9.919 ms 10.052 ms 11 cr2-pos-0-0-5-0.sanfrancisco.savvis.net (204.70.200.194) 83.281 ms 82.172 ms 82.575 ms 12 pr1-so-0-0-0.PaloAltoPaix.savvis.net (204.70.200.193) 80.832 ms 82.515 ms 81.396 ms 13 pr3-so-0-0-0.PaloAltoPaix.savvis.net (204.70.199.106) 80.805 ms 81.499 ms 80.664 ms 14 206.24.241.202 (206.24.241.202) 94.556 ms 89.078 ms 90.265 ms 15 pr3-ge-3-0-0.PaloAltoPaix.savvis.net (206.24.241.201) 82.002 ms 81.618 ms 81.731 ms 16 206.24.241.202 (206.24.241.202) 82.548 ms 85.024 ms 90.215 ms 17 pr3-ge-3-0-0.PaloAltoPaix.savvis.net (206.24.241.201) 83.186 ms 84.437 ms 83.145 ms 18 206.24.241.202 (206.24.241.202) 94.735 ms 89.556 ms 89.939 ms 19 pr3-ge-3-0-0.PaloAltoPaix.savvis.net (206.24.241.201) 83.556 ms 84.091 ms 85.894 ms 20 206.24.241.202 (206.24.241.202) 88.289 ms 90.290 ms 89.362 ms Thanks, Craig ________________________ Craig Holland Rhythm NewMedia Sr. Director Operations & Integration YIM: cholland

Re: REJECT-ON-SMTP-DATA (Re: Mail Server best practices - was: Pandora's Box of new TLDs)
by Jean-François Mezei 05 Jul '08

05 Jul '08

one note about whether to filter at receiving SMTP server or later. The receiving SMTP server is the one that has the conversation with the sender. Rejecting mail from servers having an un-backtranslatable IP is best done right away by the receiving server right after the HELO command by issuing error message about the IP being unbacktranslatable. Reduces the load. later on (for instance at the client level), you need to parse the RFC822 text header and there are some bits that are missing, notably the RCPT TO: commands. This is especially true when the "TO" in the 822 header is faked. Blocking messages as early as possible also greatly reduces the load on your system, disk storage requirements etc.

Replacement for Avaya CNA/RouteScience
by Drew Weaver 05 Jul '08

05 Jul '08

Howdy for reasons it might be inappropriate to discuss on this list we've decided that we're going to replace our Avaya/RouteScience box and we're looking for recommendations on different solutions for 'BGP management appliances'. We're aware of the Internap FCP product, but is there anything else out there besides 'oy, hire a BGP admin ya tool!' that anyone can offer? As always, comments are appreciated. -Drew

ICANN opens up Pandora's Box of new TLDs
by Jim Popovitch 05 Jul '08

05 Jul '08

Two years ago I posed the question here about the need for TLDs (http://www.mcabee.org/lists/nanog/May-06/msg00110.html) I summerizsed that companies IP (Intellectual Property) guidelines would never allow domain.org to exist if they owned domain.com (ibm.org vrs ibm.com) I felt that TLDs really represented a monetary harvesting scheme as every new TLD forced companies to "pay for yet another domain name" (slowly milking businesses). At that time several knowledgeable folks commented that TLDs were necessary in the beginning due to the need to distribute queries. Now it seems, ICANN has decided to add a new paradigm :-) How will a TLD like .ibm be handled now, and how is this different than what I proposed in 2006? -Jim P.

RIPE NCC will begin allocating from 188/8
by Alex Le Heux 03 Jul '08

03 Jul '08

Dear Colleagues, The IANA and the RIRs are working on an ongoing basis to verify and correct registration data of legacy address space to identify free space in these blocks. As a result of this work the RIPE NCC will begin allocating from 188/8 in future. The minimum allocation size for 188/8 has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found at: https://www.ripe.net/ripe/docs/ripe-434.html Please also note that three "pilot" prefixes will be announced from 188/8. These prefixes are: 188.0.0.0/16 188.0.0.0/21 188.0.0.0/24 They will all originate in AS12654. The following pingable addresses will available in these blocks: 188.0.8.1 188.0.1.1 188.0.0.1 More information on this "pilot" activity is available in the document "De-Bogonising New Address Blocks", which can be found at: http://www.ripe.net/ripe/docs/ripe-351.html Best regards, Alex Le Heux RIPE NCC
