The Registered Ports are listed by the IANA and on most systems can be
used by ordinary user processes or programs executed by ordinary
users.

Ports are used in the TCP [RFC793] to name the ends of logical
connections which carry long term conversations. For the purpose of
providing services to unknown callers, a service contact port is
defined. This list specifies the port used by the server process as
its contact port.

The IANA registers uses of these ports as a convenience to the
community.

To the extent possible, these same port assignments are used with the
UDP [RFC768].

The Registered Ports are in the range 1024-49151.
Could be used for most anything - you would have to do some more investigating on your server - post your OS and version so the correct commands may be given to possibly scan ports.

NAME
named.star - Defines data used by named to initialize the BIND (Berkeley Internet Name Domain) name server file SYNOPSIS
/etc/namedb/named.* DESCRIPTION
The data files referenced in the named.conf file can have any names, but they are generally given names of the form /etc/namedb/named.*. This naming convention is used for convenience in maintaining the named daemon's file. The records in the named data files are called resource records. Except for comments (starting with a ; (semicolon) and continuing to the end of the line), the resource records in the data files generally follow the format of the resource records that the named daemon returns in response to queries from resolver routines. The named.conf file is the default configuration (or boot) file for the named server. The named daemon reads the start-up file when the named daemon starts and when receiving the signal SIGHUP. EXAMPLES
The following examples portray two domains on two different networks: Domain abc.aus.osf.com, Internet address 192.9.201.n (where n varies for each system on the network) Domain xyz.aus.osf.com, Internet address 128.114.100.n (where n varies for each system on the network) In this sample configuration, both the primary and the secondary name servers are in the abc.aus.osf.com domain, and host hera is the gateway host. The following are sample entries in a named.ca file: ; root name servers. 1 IN NS relay.osf.com. relay.osf.com. 3600000 IN A 129.114.1.2 The following two files are sam- ple entries from the named.data files for hosts venus and allen. (The data files can have any name you choose, as long as that name is defined in the named.boot file. In this case, the names are named.abcdata and named.xyzdata.) The named file for host venus is in the following file, called named.abcdata: ;OWNER TTL CLASS TYPE RDATA ;local domain server is venus @ IN SOA venus bob.robert.abc.aus.osf.com. ( 1.1 ;serial 3600 ;refresh 600 ;retry 3600000 ;expire 86400) ;minimum IN NS venus IN NS kronos IN MX 10 venus.abc.aus.osf.com. ; address for local loopback localhost IN A 127.1 ; address of machines in the same domain venus IN A 192.9.201.1 venus IN A 128.114.100.1 venus IN MX 10 venus.abc.aus.osf.com. veabc IN CNAME venus IN WKS 192.9.201.1 udp (tftp nameserver domain) IN WKS 192.9.201.1 tcp (echo telnet smtp discard uucp-path systat daytime netstat chargen ftp time whois finger hostnames domain) ; delimiter for WKS kronos IN A 192.9.201.2 krabc IN CNAME kronos hera IN A 192.9.201.5 IN A 128.114.100.5 robert IN A 192.9.201.6 ernie IN A 192.9.201.7 IN HINFO HP-800 OS1 robert.abc.aus.osf.com.
