My memory has pointed me to how the .253 address came into being. See How can I get mytools.management to work with HAproxy . In the end, for that problem I used a workaround of not using a split DNS for the webserver, but in getting there I initially went down the alias route, hence 172.17.2.253. So adamOne has a long memory? How can I make it forget? It is not in /usr/local/etc/adamone/anmuscle.conf or anywhere else in pfSense.
Also it does not explain the 261 address at all.
