I have 2 Ip addresses in my Linksys Wireless B router's advanced routing table???? Can someone explain what they are?

They are both 211 hops away and the subnet for them is 16.140.0.0 and the gateway is 52.211.2.208

Both these show up:
64.118.29.208
242.26.7.208

NetType: IANA Special Use
Comment: Please see RFC 3330 for additional information.

That is the comment from WhoIS..... What are these computers.... they show up very strange results from Tracert or Ping.......

If anyone could help me figure out what they are doing on my routing table... I would be able to sleep better at night.... I gotta go to bed but I still haven't found anything out that really explains what they are doing in my router. I noticed them yesterday but it was the first time I have seen them.
