ATM
by Philip Lavine 07 Jul '05

07 Jul '05

I plan to design a hub and spoke WAN using ATM. The data traversing the WAN is US equities market data. Market data can be in two flavors multicast and TCP client/server. Another facet of market data is it is bursty in nature and is very sensitive to packet loss and latency (like voice). What type of ATM AAL format would be best for this topology? Is there any other concerns I should be aware of. Thx, Philip __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I went to http://www.iana.org/assignments/ipv4-address-space and grep-ed for APNIC (Asia-Pacific Network Information Center) to get the following list. For the church email site that I support I block wholesale /8 IP address ranges.

It belonged to some Canadian ISP, I believe it was a cable company. Regarding the aggregation/deaggregation mess. This is due to the fact that ARIN is rather strict with IP assignements and how we route internally. Because ARIN wants us to use 80% of our ip blocks, before we can request new assignments from them we have to dole out addresses in /22's to each city we have, in order to use them up appropriately. Its been a bit of a nightmare trying to meet ARIN's policies and also try to meet the Internet Communities policies. Believe me, I would much rather advertise a /16 prefix out to the Internet, rather then a /22. We have not been able to accommodate this unfortunately. -----Original Message----- From: Jon Lewis [mailto:jlewis@lewis.org] Sent: Wednesday, July 06, 2005 10:31 AM To: Sanfilippo, Ted Cc: nanog(a)merit.edu Subject: Re: SORBs On Wed, 6 Jul 2005, Sanfilippo, Ted wrote: > Does anyone know of an easier way to remove IP blocks from a blacklist? > We received a /16 from ARIN in May and have been trying to get SORB's > to remove the blacklist association on these addresses.

Any chance of this deaggregation mess getting cleaned up? I've contacted sorbs on your behalf, assuming the /16 concerned is 63.138.0.0/16. This raises a question that interests me as someone who had to deal with recently bogon space last time I got ARIN space. 63/8 was assigned to ARIN in 1997. Much of it appears to have been assigned to ARIN members in the late 90s and very early 2000's. How did Paetec happen to get a /16 from 63/8 in 2005? Was this recently reclaimed from some defunct company (which could explain the sorbs dul listing), and Paetec just got lucky? ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

Enable BIND cache server to resolve chinese domain name?
by Joe Shen 06 Jul '05

06 Jul '05

Hi, Some of our customer complaint they could not visit back to their web site, which use chinese domain name. I google the net and found some one recommend to use public-root.com servers in hint file. I found domain name like xn--8pru44h.xn--55qx5d could not be resolved either. Our cache server runs BIND9.3.1 with root server list from rs.internic.net. Do I need to modify our cache server configuration to enable it? regards Joe __________________________________ Meet your soulmate! Yahoo!

Re: Report: Major Newspaper Sites Hobbled by Power Woes
by MARLON BORBA 06 Jul '05

06 Jul '05

This leads us to the old fact that several ISPs and hosting providers protect their servers with every network perimeter security resource (firewalls, IPSs, virus-and-spam-appliances etc) but forget that "availability" as a security principle requires adequate physical and utility safeguards also (backup site, automated failover, redundant communication links between sites and backbones, capable UPS, air-conditioning, fire-extinguishing...). Not all, as you see, are computer-related "per se", but they are "sine-qua-non" for 24x7 availability.
