At Institute of Science Tokyo, in order to use the campus network (STNET), each academic and administrative unit must first apply for and obtain the necessary resources. If your unit was already using the network before the university integration, you can in principle continue using it.
When each organization manages and operates the network it has obtained, the network can be subdivided by campus or by purpose, and a communications policy can be applied to each segment.
The organizational unit for applications and inquiries is the academic/administrative unit. Applications on a per-room or per-laboratory basis are not accepted. If anything is unclear, please first check within your own organization.
For more details, please consult each of the pages below.
Domain Application
At ScienceTokyo, domain use has been unified under the "unit domain" scheme.
If you have any questions, please first check the status and policy of your own organization, and then contact us individually.
About the New Domain Services
Some domains that were used at the predecessor universities can no longer be operated directly under isct.ac.jp. To accompany this change, dedicated domains have been set up for university-wide services that are difficult to operate under a single unit, as well as for outreach use by courses and projects. Please consider using them as appropriate.
| Domain | Intended Use | Example Host |
|---|---|---|
s.isct.ac.jp | University-wide services; for organizations in the School of Medical and Dental Sciences | servicename.s.isct.ac.jp |
p.isct.ac.jp | Project outreach, etc. | projectname.p.isct.ac.jp |
i.isct.ac.jp | Items spanning multiple units; for courses | coursename.i.isct.ac.jp |
About Domains from the Predecessor Universities
Unit domains and similar from the predecessor universities will be maintained for the time being. Mail and websites using those domains can continue to be used, but we strongly encourage you to take this opportunity to plan a phased migration.
Decisions about whether and when these domains will be retired or maintained will be made in accordance with the ScienceTokyo policy, taking the post-integration migration status into account. Such decisions will be announced together with an appropriate grace period.
STNET Application
This is the application for obtaining IP addresses for use on STNET. The applicant must be an academic or administrative unit (such as a School or the central administration). Applications cannot be made by individual laboratories or smaller units; please contact the designated liaison of your parent organization.
If a newly established organization (equivalent to an academic/administrative unit) requires network resources, please first consolidate within your organization the campus to be used, the number of IP addresses required, and the type of addresses (global or private), and then contact us.
When the person in charge changes (e.g. due to a personnel transfer), please be sure to submit a change application. As a rule, for security and management/operational reasons, our group communicates only with the designated liaison in charge. We appreciate your understanding.
IPv6 Service
For IPv6, the numbering plan for IPv6 addresses was revised in FY2022, and per-organization allocations have been prepared.
For applications and inquiries regarding IPv6 addresses, please contact the NOC (Center for Information Infrastructure).
Services Related to Communications Policy
Firewall Service
With the Firewall Service, two types of policies can be set per network: a network policy and an exception policy. For each policy, the outbound (from the user's subnet to outside the university) and inbound (from outside the university to the user's subnet) settings can be selected from a predefined set of services.
For a given subnet, only one of the Firewall Service and the Screening Service can be used; the two cannot be combined on the same subnet.
Screening Service
This is a service that, at the connection point between the on-campus network backbone of the School of Science and Engineering and the external network, configures permit/deny settings on a per-host basis to restrict communication between on-campus and off-campus hosts.
By default, each host at the university is configured so that communication with the external network is not permitted.
Domestic-Only Filter Service
This is a service that limits inbound connections to specified IP addresses
