No.
I am using an old school sunos if that makes a difference.
I was using nslookup. This is what my manpage says. Doesn't things in brackets mean optional?
NAME
nslookup - query Internet name servers interactively
SYNOPSIS
nslookup [-option] [name | -] [server]
DESCRIPTION
nslookup is a program to query Internet domain name servers. nslookup
has two modes: interactive and non-interactive. Interactive mode allows
the user to query name servers for information about various hosts and
domains or to print a list of hosts in a domain. Non-interactive mode
prints just the name and requested information for a host or domain.
ARGUMENTS
Interactive mode is entered in the following cases:
a. when no arguments are given (the default name server is used);
b. when the first argument is a hyphen (-) and the second argument is
the host name or Internet address of a name server.
Non-interactive mode is used when the name or Internet address of the
host to be looked up is given as the first argument. The optional sec-
ond argument specifies the host name or address of a name server.
Options can also be specified on the command line if they precede the
arguments and are prefixed with a hyphen. For example, to change the
default query type to host information, with an initial timeout of 10
seconds, type:
nslookup -query=hinfo -timeout=10
The -version option causes nslookup to print the version number and im-
mediately exit.
I thought things in brackets was optional? So I did not provide it a server. It seemed to freeze so I pressed ctrl + c. Then nothing seemed to work. It also left a caret > on the screen. The colon is part of my terminal :. It does not bother me so I have not changed it.

Some googling gave me the idea to type reset. Not sure why that helps. Had to type that a few times for it to work.

-bash: kijsal: command not found
-bash: kmreset: command not found

I also googled ctrl + q after you mentioned it above. I found this.

This seemed to help. Not sure why ctrl + \ is better than ctrl + c.
<kbd>ctrl-\</kbd>
same as ctrl-c but stronger (used when terminal doesn't respond)
This was the output after I typed ctrl + \.
