Problems with BARRNET network 131.119.250.119

[xladm () xlink net]

Our mailer tries to deliver mail to 131.119.250.119 (bargate.silvaco.com,
SILVACO.BARRNET.NET) and gets host unreachable. Routes for 131.119.0.0 are 
given as:

gw3#sh ip ro 131.119.0.0
Routing entry for 131.119.0.0 (mask 255.255.255.0), 2 known subnets
  Redistributing via igrp 51771

Is it useful to add Class-B-Subnets to the routing table whilst we are
trying to reduce Class-C entries?

Regards,

Arnold
