Smallest IPv4 allocation size (in the RIPE region)?
As I understand it, IPv4 route announcement smaller than a /24 do not propagate very well, if at all. I have thus been surprised to see the following blocks listed separately as "allocated" in the daily "stats" file for RIPE. Can anyone explain to me why these small IPv4 blocks are listed in there separately? (Note: I have found no such small blocks in the daily stats files for any of the other four Regional Internet Registries... only RIPE seems to have such things.) 91.227.79.0/25 ripe 91.227.79.128/25 ripe 156.67.6.0/29 ripe 156.67.6.8/29 ripe 156.67.6.16/29 ripe 156.67.6.24/29 ripe 156.67.6.32/29 ripe 156.67.6.40/29 ripe 156.67.6.48/28 ripe 156.67.6.64/26 ripe 156.67.6.128/25 ripe 185.30.232.0/26 ripe 185.30.232.64/26 ripe 185.30.232.128/25 ripe 193.34.192.0/25 ripe 193.34.192.128/25 ripe 193.34.193.0/25 ripe 193.34.195.0/25 ripe 193.34.195.128/25 ripe 193.34.196.0/25 ripe 193.34.197.0/25 ripe 193.34.197.128/25 ripe 193.34.198.0/25 ripe 193.34.198.128/25 ripe 193.34.199.0/25 ripe 193.34.200.0/25 ripe 193.34.200.128/25 ripe 193.34.203.0/25 ripe 193.34.203.128/25 ripe 193.43.0.0/26 ripe 193.43.0.64/27 ripe 193.43.0.96/27 ripe 193.43.0.128/25 ripe 193.58.0.0/27 ripe 193.58.0.32/28 ripe 193.58.0.56/29 ripe 193.58.0.64/26 ripe 193.58.0.128/25 ripe 193.164.232.0/26 ripe 193.164.232.64/27 ripe 193.164.232.160/27 ripe 193.164.232.192/27 ripe 193.188.134.0/26 ripe 193.188.134.64/27 ripe 193.188.134.96/28 ripe 193.188.134.112/29 ripe 193.188.134.120/29 ripe 193.188.134.128/29 ripe 193.188.134.144/28 ripe 193.188.134.160/29 ripe 193.188.134.168/29 ripe 193.188.134.176/28 ripe 193.188.134.192/29 ripe 193.192.12.128/25 ripe 193.201.144.0/25 ripe 193.201.144.128/25 ripe 193.201.145.0/25 ripe 193.201.146.0/25 ripe 193.201.146.128/25 ripe 193.201.147.0/26 ripe 193.201.147.64/27 ripe 193.201.147.96/27 ripe 193.201.147.128/27 ripe 193.201.147.160/27 ripe 193.201.147.224/27 ripe 193.201.148.0/26 ripe 193.201.148.64/26 ripe 193.201.148.192/26 ripe 193.201.149.64/26 ripe 193.201.149.192/26 ripe 193.201.150.0/26 ripe 193.201.150.64/26 ripe 193.201.150.128/26 ripe 193.201.151.0/26 ripe 193.201.151.192/26 ripe 193.201.152.0/25 ripe 193.201.152.128/25 ripe 193.201.154.0/25 ripe 193.201.154.128/25 ripe 193.201.155.128/25 ripe 193.201.156.0/25 ripe 193.201.156.128/25 ripe 193.201.157.0/25 ripe 193.201.159.128/25 ripe 193.218.205.0/26 ripe 193.218.205.64/26 ripe 193.218.205.128/26 ripe 193.218.205.192/27 ripe 193.218.207.0/28 ripe 193.218.207.16/28 ripe 193.218.207.32/27 ripe 193.218.207.80/28 ripe 193.218.207.96/27 ripe 193.218.207.128/25 ripe 193.243.183.64/26 ripe 193.243.183.192/26 ripe 193.254.23.0/25 ripe 193.254.23.128/25 ripe 194.42.47.128/25 ripe 194.42.55.0/27 ripe 194.42.55.32/27 ripe 194.42.55.64/26 ripe 194.42.55.128/27 ripe 194.42.55.160/27 ripe 194.42.55.192/27 ripe 194.42.55.224/27 ripe 194.55.1.0/25 ripe 194.55.1.128/25 ripe 194.93.123.128/25 ripe 194.117.50.128/25 ripe 194.117.52.0/25 ripe 194.117.53.128/25 ripe 194.117.54.0/25 ripe 194.117.54.128/25 ripe 194.117.55.128/25 ripe 194.153.152.0/25 ripe 194.153.152.128/25 ripe 194.153.153.128/25 ripe 194.153.154.0/25 ripe 194.153.154.128/25 ripe 194.153.156.0/26 ripe 194.153.156.64/26 ripe 194.153.156.128/25 ripe 194.153.157.128/27 ripe 194.153.157.160/27 ripe 194.153.157.192/26 ripe 194.153.158.128/25 ripe 194.153.159.0/26 ripe 194.153.159.64/26 ripe 194.153.215.0/25 ripe 194.153.215.128/25 ripe 194.180.159.240/28 ripe 194.180.226.152/29 ripe 194.246.39.96/27 ripe 194.246.39.128/26 ripe 194.246.39.224/27 ripe 195.13.37.0/25 ripe 195.13.46.0/25 ripe 195.13.46.128/25 ripe 195.35.104.32/27 ripe 195.35.104.64/26 ripe 195.35.104.128/25 ripe 195.60.80.96/27 ripe 195.60.80.128/27 ripe 195.60.80.160/27 ripe 195.60.80.192/27 ripe 195.60.80.224/27 ripe 195.60.81.0/26 ripe 195.60.81.64/26 ripe 195.60.81.192/26 ripe 195.60.82.0/26 ripe 195.60.82.64/26 ripe 195.60.82.128/26 ripe 195.60.82.192/26 ripe 195.60.83.0/27 ripe 195.60.83.64/27 ripe 195.60.83.96/27 ripe 195.60.83.160/27 ripe 195.60.83.192/27 ripe 195.60.83.224/27 ripe 195.60.84.0/25 ripe 195.60.85.0/25 ripe 195.60.87.0/25 ripe 195.60.87.128/25 ripe 195.60.89.0/25 ripe 195.60.89.128/25 ripe 195.60.90.0/25 ripe 195.60.90.128/25 ripe 195.60.91.0/25 ripe 195.60.92.0/26 ripe 195.60.92.64/26 ripe 195.60.92.128/26 ripe 195.60.93.0/26 ripe 195.60.93.128/26 ripe 195.60.93.192/26 ripe 195.60.95.0/25 ripe 195.60.95.128/25 ripe

My apologies. A mere slip of the tongue on my part. I had intended to say "assigned"... not "allocated".

Regardless of the exact status, I remain perplexed to see blocks with prefix lengths greater than /24 in the daily RIPE stats file. Regards, rfg

not sure why you're perplexed? They're legitimate assignments. The public DFZ isn't the only game in town. Nick
