As Chris mentioned, the options that exist in macports.conf are host_blacklist
and preferred_hosts. But the question is: why do you want to restrict this?

What do you mean by "download ports"?
MacPorts base updates will only be downloaded from the rsync server specified
in rsync_server in macports.conf. So you can change this to a closer mirror if
you want to. You can see a list of available mirrors at
https://trac.macports.org/wiki/Mirrors
Similarly, the portfile definitions (the ports tree) will only be downloaded
from the source you specify in sources.conf.
If MacPorts is installed in the normal /opt/local prefix and certain options in
macports.conf are set at their default values, then when you request to install
ports, MacPorts will try to download binaries/packages/archives of them. The
servers from which it will try to download binaries are specified in the
_resources/port1.0/fetch/archive_sites.tcl file in the ports tree. MacPorts
will try them in ascending order by ping time, so the servers closest to you
will be tried first and there should be no need to override this, but if you
need to exclude one or more servers that are misbehaving, you can blacklist
them by adding them to host_blacklist in macports.conf. And if you want one or
more of these servers to be tried first, regardless of ping time, you can add
them to preferred_hosts.
If a binary of a port is not available or if you have configured MacPorts not
to use binaries, then the port will build from source. The source code will be
downloaded from the server(s) specified in the Portfile and/or the
_resources/port1.0/fetch/mirror_sites.tcl file in the ports tree. Same as
above, they're tried in ping order, so MacPorts should already be picking the
best server for you automatically. Same as above, you could use host_blacklist
to prevent a "bad" server from being used, but you would only really use that
if there was something unique about your network situation that makes a server
"bad" for you but not for anybody else; obviously if a server were "bad" for
everybody we'd remove it. You could also use preferred_hosts, for example to
give a preference to distfiles.macports.org or a closer MacPorts mirror, if for
some reason you really don't want to download from a different server that
might be closer to you and therefore faster. If a file is not available on your
preferred server(s), MacPorts will try to download from other servers (unless
they're blacklisted). There are a few ports for which we cannot mirror the
source code, because they can only fetch their source code from a single server
(a repository using git, hg, svn, etc.), so there's nothing that can be
usefully configured about that; if you've blacklisted that one server, then you
won't be able to build that port.
