I like my DME to be as close to base malt as possible. 2-row base malt hovers around 34-37 ppg and 2 L. With this important fact in mind, you must also consider the different characters of English vs. American 2-row. The English variety is slightly more characterful and complex, whereas the American variety is more clean and neutral. Both can be good in an IPA, but it really depends on the brewer's preference. If you want an IPA with decent malt presence, then the American variety needs a little more help from other malts whereas the English variety will be good on it's own or with minimal help. If you want an IPA with clean or very low malt presence, then go with the American variety along with some corn sugar. Pilsener DME is completely different in character than 2-row. If you want that bready, biscuity, clean, pils character, then go for it. You can use any of these four in an IPA...
Briess Pilsen Light = 44 ppg / 2 L = (probably contains American Pils Malt and Carapils)
Briess Golden Light = 43 ppg / 5 L (probably contains American 2-row, Carapils, and maybe some Light Crystal)
Muntons Light = 44 ppg / 5 L (probably contains English 2-row, Carapils, and Light Crystal)
Muntons Extra Light = 37 ppg / 3 L (probably contains English 2-row and a touch of Carapils)
I prefer Muntons Extra Light myself. Mix it with some American 2-row, wheat malt, corn sugar, maybe a touch of light crystal (although not necessary) and you have a great, clean, characterful foundation that isn't too sweet. I also find that since it offers the lowest ppg, that it tends to ferment out better than the others, leaving you with a drier IPA, which I prefer.
