SFTP Arcana.....

We are currently using SFTP to communicate with Wells Fargo. Certificates
are in place and the process is working. Wells Fargo has notified us of a
pending change to their IP addresses, and advised that we use just their
domain name and not their IP addresses.

When I look at the known_hosts file, I see that we have entries as
follows:

safetrans.wellsfargo.com,151.151.XX.XXX ssh-rsa longencyptionstring
safetransvalidate.wellsfargo.com,151.151.XX.XXX ssh-rsa
longencryptionstring
151.151.XX.XX ssh-rsa longencryptionstring

Is there a way for me to modify these entries with URLs to take out the IP
addresses? I know that the system is able to resolve the URLs back to the
IP addresses, which is what Wells Fargo advises. (Ping and Trace Route
both resolve back to the correct addresses.) When I use green screen edit
file to simply remove the IP address, the process stops working, possibly
because deleting the address causes part of the encryption string to shift
left, but leaves a gap within the encryption string. It doesn't help that
my Google powers are failing me at finding a specification for the layout
of this file.
