Hi.
I've got a couple of dell servers with lifecycle controller in our datacenters.
When I'm trying to do a firmware upgrade from ftp.dell.com I've noticed it's connecting to 2 ip addresses on ftp 143.166.135.76 and 143.166.147.76
We have a strict outbound policy via a squid proxy server where ftp://143.166.135.76(.*)?$ and ftp://143.166.147.76(.*)?$ are allowed.
I've noticed that after the lifecycle controller firmware updated itself, on my next upgrade attempts, it tries to connect to ftp://[143.166.135.76]/.... and ftp://[143.166.147.76]/... (note the square brackets) via my proxy server:

on older versions it's connecting to the same ips but without " [ ... ] "
Is there a genuine reason for adding square brackets into the ftp address ?
Thanks,
Istvan
