One more thing to elaborate, we have our own DDoS mitigation equipment, and it is located in the edge of the network nearest to the high capacity Internet circuits to minimize the local transit cost.

ISP in NYC
by Dovid Bender 17 Jul '15

17 Jul '15

Hi, We are looking to peer with another ISP in NY. My options are: Telia Tata Cogent We currently have (and will keep): HE NTT TELX (They use NTT and HE and we are looking to replace them). We need an ISP that has a good peering/connectivity in Europe and Asia (Israel specific). Any advice on who to go with?

IPv6 CPE best practices
by Chuck Church 16 Jul '15

16 Jul '15

So, I've been following this IPv6 discussion for a while now. Putting much more thought into it than ever before. What I've gathered so far: We need both SLAAC and DHPCv6 on CPE router to support all end clients. Android and some other platforms still have some issues with a v6-addressed DNS server (or don't use DHCPv6 at all), so you really need your v4-addressed DNS server to hand out both AAAA and A records together. Is that close? So giving each customer a /48 is the way to go. How does one go about configuring CPEs for devices to use this? I'm aware of how DHCP-PD can dish out a /48 of a larger block. Should I move to a standard CPE that supports DHCP-PD (here is a list: https://getipv6.info/display/IPv6/Broadband+CPE , some mention PD)? Or should I just allow them to use any IPv6 compatible router, and issue each customer a /48, but only configure a /64 of that block for each CPE's inside interface (manual config). Is there anything other than DHCP-PD that can do this auto-magically? I support a small WISP occasionally, it's all wireless and Ethernet. Several hundred small business customers. Nothing super complicated. Been playing with an HE tunnel the last few days and found my netflow collector works fine with FNF and IPv6, so making some progress. Just wanting to avoid any big mistakes when we think about getting some customers on it. Thanks, Chuck

Speaking of NTP...
by Matthew Huff 16 Jul '15

16 Jul '15

We have 5 NTP server: 2 x stratum 1 rubidium oscillator time servers with GPS sync, and 3 servers running NTP 4.2.6p5-3 synced to external internet based NTP stratum 1 servers. We monitor our NTP environment closely, and over the last 10+ years, normally all of our NTP servers are sync'ed within +/- 2 msec. Starting last Friday, we started seeing some remote NTP servers with GPS reference consistently offset by 10 msec. Any one else seeing this? ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669

Re: 'gray' market IPv4
by Seth Mos 16 Jul '15

We had the same thing finding a broker for a /24 pi in the RIPE region. Not all of the brokers have the size you want, eg a /20 when you need a /24. It ends up being between 2500 to 4000 euros depending on notary fees and if you already have a LIR agreement.

Re: Remember "Internet-In-A-Box"?
by Seth Mos 16 Jul '15

16 Jul '15

So, if i get this right. The problem is not quite as bad to fix. It just needs a dnscache/dnsproxy process bound to the ipv4 localhost that uses the ipv6 dns server. Basically what dnsmasq does. Biggest problem is that it wouldn't follow autoconfigure and thus require manual intervention. That is a no go for dynamic networks of any sort.

In this case, the problem isn’t the things RA does, but the things his implementation of RA doesn’t do (RDNSS). Without RDNSS, android would still be brain-damaged and unable to figure out what an IPv6 nameserver is. The only way it would be able to talk to the IPv6 internet was if it got nameservers from DHCP4. At least with RDNSS, a thin lightweight client can get nameservers on IPv6. At least with RDNSS, a network administrator that doesn’t want to have to do DHCPv6 doesn’t have to in most cases. >> The XP box is in an even worse situation if you try to run it on a >> v6-only network. > > Which is fixable with a third party DHCPv6 client / manual configuration > of the nameservers. Nope… XP’s resolver is utterly and completely incapable of transmitting an IPv6 DNS request. You _HAVE_ to have an IPv4 resolver reachable to the box or forego any idea of using DNS. Owen
