Here are the following resources and services available for use by OttIX members and their customers. (Last updated: 7 April, 2017.)


For better network security posturing and performance, OttIX sponsors a number of Top-level domain DNS servers (such as .ca) as well as root DNS servers, listed below.

AS 112:
The AS 112 Project is being hosted by OttIX. This is an anycasted instance of a special DNS root server that captures RFC 1918 DNS queries to prevent overloading of the global root DNS system.
This really important server contains the .com and other important top-level domains which improves the responsiveness of DNS queries for those zones, such as and many, many others. Provided by Verisign.
The University of Maryland has a root DNS server (one of 13 in the world, see the Root Server Operators website for more details) located at OttIX.
NASA Ames Research Center provides its root DNS server here at OttIX.
The Ottawa Internet Exchange is sponsoring an anycasted instance of the F root which can be reached by peering at OttIX or over OttIX with the F root's peering routers. This makes the Internet's main DNS infrastructure more resilient by prevent global attacks on the DNS (in particular by keeping any attack source that happens to be connected to OttIX localized.
Verisign also provides another one of the Internet's 13 DNS root servers.
The RIPE-NCC runs an anycasted instance of it European-based root server here in Ottawa within OttIX.
ICANN also operates an instance of this root server, at OttIX.
CIRA's DNS server responsible for the .CA domain is reachable via OttIX as well under a sponsorship with PCH.
OttIX provides as a service to its members secondary DNS services as added resilience against outages that they may experience, but require their name space to remain active.

Too much software to mention (Linux distros like Slackware, Debian, Fedora and SUSE, FreeBSD, GNU FTP site, GNOME, X, XFree86, Apache). Always consult the server's Status for the latest info on software available for download from there.


OttIX runs a public 6to4 relay for those wanting to use IPv6 but don't have a native IPv6 network available. Coverage extends through to Canadian universities. The routes and 2002::/16 are advertised through BGP to make this work. Statistics on this particular node's operations can be found here.


OttIX not only runs as a dual-stack IX, but also a multicast dual-stack IX. Multicast is an efficient streaming delivery method that allows for just one set of packets to be sent to multiple destinations. This differs from typical webcasting, where each client pulls its own stream from a server, consuming considerable bandwidth at the source and throughout a network. Instead, routers closet to the clients do the replication work, lessening the load on the streaming source (the server).

An OttIX-centric news-server. All newsgroups. Peering over IPv6 also available. Reading and posting access is also granted to those providers that wish to have their users go direct to the OttIX news-server, instead of running their own. This server runs cleanfeed.


NTP, or Network Time Protocol, provides for highly accurate timing synchronisation between computers and other network equipment via a computer network.
A service exlusively for our members, this server is a stratum-1 clock, synced to a real atomic clock. This server is IPv6 enabled as well.
This server is a stratum 2 server synced to three stratum 1 clocks that are hooked into atomic clocks. NRC also provides connectivity to stratum 1 servers for a fee. More information can be found at NRC's Institute for National Measurement Standards website.

RS1 and RS2:
The OttIX Route Servers also provide Stratum 2 NTP services, for those interested in using those instead.
An OttIX-supplied NTP server for members only.
An OttIX-supplied NTP server for members only.

OttIX has a local mirror of AdUni's advanced CS courses, including high bandwidth videos of lectures in Real format and selected class notes and tests.

OttIX runs its own whois registry which members can use to register their routes. This registry is mirrored by the RADB for global distribution.
