There isn't any. They are both the same file type.

Most servers have a default file list that they will go through in order to determine what page to show first. For example, if you have a list that reads "index.html, index.htm, default.html..." if there is a index.html it will be shown as the index. If not the server looks for an index.htm, if that isn't found it's onto default.html and so forth. If you have an index.html & an index.htm, the index.html is what is going to be shown on going to that domain. I'm assuming that's what you mean. Nameservers are something different.
