Assuming that this is for a telnet or SSH login to the Operating System, I suppose you could look in a few ways. The hostname command might be a start.
Alternatively, I presume that the cluster has a service IP address that everything uses and if one node becomes unavailable then the IP address is transferred, however there is also very likely one or more private IP addresses on each host that you don't publish. Which did you connect to? It is possible (but not so wise) to leave these private/boot IP addresses un-routable from the main network.
Is this a load balanced server in some way? The above will still apply.

avahi-publish-address
avahi-publish-service(1) General Commands Manual avahi-publish-service(1)
NAME
avahi-publish-service - Register an mDNS/DNS-SD service or host name or address mapping using the Avahi daemon
SYNOPSIS
avahi-publish -s [options] name service-type port [TXT data ...]
avahi-publish-service [options] name service-type port [TXT data ...]
avahi-publish -a [options] host name address
avahi-publish-address [options] host name address
DESCRIPTION
Register an mDNS/DNS-SD service or host name/address mapping using the Avahi daemon.
OPTIONS
When calling in service registration mode, specify a DNS-SD service name (e.g. "Lennart's Files"), a service type (e.g. _http._tcp) and an
IP port number for the service, optionally followed by any number of TXT record strings on the command line. When calling in address/host
name registration mode specify a fully qualified host name and an address (IPv4 or IPv6).
-s | --service
Register a service. avahi-publish-service is equivalent to avahi-publish -s.
-a | --address
Register an address/host name mapping. avahi-publish-address is equivalent to avahi-publish -a.
-v | --verbose
Enable verbose mode.
-H | --host= HOSTNAME
Specify a host name for this service, in case it doesn't reside on the local host. This host name needs to be fully qualified and
resolvable using mDNS or unicast DNS.
-d | --domain= DOMAIN
Publish the service in the specified domain. If omitted the Avahi daemon will publish it in its default domain (usually .local).
--subtype= SUBTYPE
Register the service with an additional subtype in addition to the main type. DNS-SD subtypes have the form _anon._sub._ftp._tcp,
where _anon is the identifier of the subtype and _ftp._tcp is the main type. You may pass this option multiple times to register the
service with multiple subtypes.
-f | --no-fail
Don't fail if the daemon is not found running. Instead, wait until it appears. If it disconnects, try to reconnect.
-h | --help
Show help
-V | --version
Show version information.
