  • Network - DNS and DHCP
    03/19/2015 - 08:00am to TBD

    Update 2: This maintenance was completed on THUR 3/19 @ 830AM. 

    Update: This maintenance has been postponed until Thursday March 19th starting at 8:00AM. 

    CUIT has deployed new DNS infrastructure.  As part of that deployment, we changed the IP addresses of our internal DNS resolvers to 128.59.1.3 & 128.59.1.4. 

    ​Over the last year, CUIT has reached out to departmental/IT administrators ​to inform them of the change and have asked them to notify end-users of the DNS configuration change.  

    On Tuesday March 17th, 2015 at 8:00AM
    ​, t​he legacy CUIT DNS resolvers (128.59.59.70 & 128.59.62.10) will be retired.
    ​Users/clients that continue to query the legacy CUIT DNS resolvers will not be able to reach the Internet
    ​.

    If your device/system is configured using DHCP (which we recommend), the migration to the new DNS resolvers
    ​ has already taken place and you should not need to take any action.


    However, if you are not using DHCP and have statically configured your IP address and DNS server configuration, you will need to update your DNS server configuration to reflect the new DNS 
    ​resolvers: 128.59.1.3 & 128.59.1.4.

    Note: users may have to reboot their devices/systems for their new DNS 
    ​configuration ​settings to take effect.

    Please contact the CUIT Service Desk at 212-854-1919 for assistance if you make the DNS server configuration change and continue to experience issues connecting to the Internet.
