Why do I have redundant routing in Windows 7?
- by Mark
I'm trying to better understand my routing tables. My routing table is:
IPv4 Route Table
===========================================================================
Active Routes:
Network Destination Netmask Gateway Interface Metric
1. 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.151 25
2. 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306
3. 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306
4. 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306
5. 192.168.1.0 255.255.255.0 On-link 192.168.1.151 281
6. 192.168.1.151 255.255.255.255 On-link 192.168.1.151 281
7. 192.168.1.255 255.255.255.255 On-link 192.168.1.151 281
8. 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306
9. 224.0.0.0 240.0.0.0 On-link 192.168.1.151 281
10. 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306
11. 255.255.255.255 255.255.255.255 On-link 192.168.1.151 281

Most of those entries make sense to me, but a few confuse me:
2 and 3 seem redundant, as do 2 and 4. Why not just 2?
5 and 6 seem redundant, as do 5 and 7. Why not just 5?
I'm trying to grok routing tables and this bit is still confusing me.
