         Relocation of the MITRE Mailbridge to Andrews AFB

1.  Now that the mailbridge at PSN 246 and CISCO IPR at Ft Detrick are
    operational, DISA is relocating the mailbridge at PSN 17 to Andrews
    AFB, PSN 67.  The new mailbridge address is 26.1.0.67. It should become
    effective on 22/Feb/92 during the early afternoon.  All gateways or 
    hosts using 26.20.0.17 as their primary or secondary mailbridge, i.e.,
    source of external gateway protocol (EGP) updates, should convert to 
    the 26.1.0.67 mailbridge.  

2.  This does not affect the NSFNET gateway addresses.  The FIX-East gateway
    into NSFNET remains 26.29.0.54.  The FIX-West NSFNET gateway remains
    26.20.0.16.  Any gateways or hosts using a default route for FIX-EAST 
    should already be using 26.29.0.54.

3.  All gateways and hosts converting to 26.1.0.67 should verify proper
    operations on Monday, 24/Feb/92.  If DISA has installation problems,
    we will announce that ASAP.  However, all gateways and hosts using the 
    new address should be prepared to use their secondary mailbridge if 
    required. 

4.  MAILBRIDGES provide either full updates or limited updates.  Currently,
    full updates are provided by the following:
   
              BMILAMES (26.20.0.16)
              BMILMITR (26.20.0.17) and
              BMILRAND (26.1.0.51)

    The following mailbridges provide limited updates:

              BMILRICH (26.3.0.246)
              BMILISI  (26.6.0.103)
              BMILDCEC (26.21.0.104)
              BMILOAK  (26.1.0.148)

    As soon as it is operational, BMILANDW (26.1.0.67) will provide full 
    updates.

    Gateway or host administrators who are uncertain whether their systems 
    should receive full or limited updates should contact the CONUS MILNET 
    Monitoring center at the number(s) given in paragraph 5 for assistance.

4.  DISA POC is Ted A. Tatchio, DDN MILNET Manager, DSN 222-7580, commercial
    (703)692-7580, e-mail address: milnetmgr@ddn-conus.ddn.mil.  Host and 
    gateway administrators experiencing problems with the new address
    (26.1.0.67) should initially contact the CONUS Monitoring Center, 
    commercial 1-800-451-7413, or DSN 222-2268, or DSN 222-5726.  All other
    questions or comments should be directed to Maj. Tatchio.
