## block of RFC1918 private-use addresses allocated from the Cambridge G-RIN.
## The former are as follows.
##
-## 81.2.113.195, 81.187.238.128/28
+## 81.2.113.195, 81.187.238.128/28, 217.169.12.64/28
## House border network (dmz). We have all of these; the loose
## address is for the router.
##
-## 212.13.18.64/28
-## Jump colocated network (jump). .65--68 are used by Jump
-## network infrastructure; we get the rest.
-##
## The latter is the block 172.29.196.0/22. Currently the low half is
## unallocated (and may be returned to the G-RIN); the remaining addresses
## are allocated as follows.
## 172.29.198.0/24 Untrusted networks.
## .0/25 house wireless net
## .128/28 iodine (IP-over-DNS) network
+## .144/28 hippotat (IP-over-HTTP) network
## .160/27 untrusted virtual network
##
## 172.29.199.0/24 Trusted networks.
## Main house range (aaisp). See below for allocation policy.
## There is no explicit DMZ allocation (and no need for one).
##
-## 2001:ba8:0:1d9::/64
-## Jump border network (jump): :1 is the router (supplied by
-## Jump); other addresses are ours.
-##
-## 2001:ba8:1d9::/48
-## Main colocated range. See below for allocation policy.
-##
## Addresses in the /64 networks are simply allocated in ascending order.
## The /48s are split into /64s by appending a 16-bit network number. The
## top nibble of the network number classifies the network, as follows.
##
## 0 No specific site: mobile VPN endpoints or anycast addresses.
## 1 House.
-## 2 Jump colocation.
## fff Local border network.
-##
-## Usually site-0 networks are allocated from the Jump range to improve
-## expected performance from/to external sites which don't engage in our
-## dynamic routing protocols.
## Define the available network classes.
