- ::ffff:1.225.106.153
Public, routable address (assignable to a host on the internet).
Could be parsed as a date. Most likely interpretation: Wednesday, January 5, 3155 (YYYYMMDD (ISO basic)).
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 31550105 first appears in π at position 773,632 of the decimal expansion (the 773,632ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
